Primaries were held Tuesday in Virginia, South Carolina, Maine, Nevada and North Dakota. In the Maine races, voters tried out a new type of voting, ranked choice voting. It allows voters to pick their candidates in order of preference.

Here are some of the notable results from Tuesday's races:

South Carolina: Mark Sanford loses to Trump-backed candidate

Over more than two decades, South Carolina voters forgave U.S. Rep. Mark Sanford for his quirkiness, his infidelity and his lies. But they could not forgive him for his criticism of President Trump.

Sanford lost his first election ever Tuesday, beaten for the Republican nomination for another term in the coastal 1st District around Charleston by state Rep. Katie Arrington. Less than three hours before the polls closed, Mr. Trump endorsed Arrington on his Twitter account with an especially personal shot at Sanford.

"Mark Sanford has been very unhelpful to me in my campaign to MAGA. He is MIA and nothing but trouble. He is better off in Argentina," the president wrote, referring to Sanford's trip to South America in 2009 to have an affair while his unknowing staff in the governor's office told reporters he was hiking the Appalachian Trail.

Sanford survived that public confession to the affair to win two more terms to the U.S. House.

But Arrington made an issue of his criticism of the president, calling him a "Never Trumper." One of her ads got personal too, saying "it's time for Mark Sanford to take a hike - for real this time."

After declaring victory Tuesday, Arrington asked Republicans to come together. And she reminded them who she thinks leads them: "We are the party of President Donald J. Trump."

Sanford won three terms for U.S. House in the 1990s, then two four-year terms as governor before the affair marred the end of his second term. He returned in 2013 and won a special election to his old U.S. House seat, holding on twice more.

Throughout his political career, Sanford has played up his outsider credentials - both in the U.S. House, where he supported a box to check on federal tax returns to put $3 toward the national debt, and as governor, bringing a pair of squealing pigs to the state House and Senate chamber to protest what he call pork spending. But Arrington, who works for a defense contractor, has exploited that trait, pointing out Sanford's call for Mr. Trump to release his tax returns, his vote against Mr. Trump's border wall proposal, and his calling proposed tariffs on alumni and steel "an experiment with stupidity."

Sanford responded that he speaks his mind regardless of party and said he has shown over two decades he is a true conservative. In his remarks Tuesday night, he said: "I stand by every one of those decisions to disagree with the president."

Then there was the Twitter post just after 4 p.m. Tuesday. After attacking Sanford, the president backed Arrington. "I fully endorse Katie Arrington for Congress in SC, a state I love. She is tough on crime and will continue our fight to lower taxes. VOTE Katie!"

Sanford is a second U.S. House member from the South attacked by a challenger for criticizing Mr. Trump. In Alabama, U.S. Rep. Martha Roby is in a July 17 runoff against former congressman Bobby Bright. Roby said two years ago that Trump's 2005 lewd comments about women, captured on an "Access Hollywood" microphone, made him "unacceptable as a candidate for president."

Arrington will take on Joe Cunningham, a construction lawyer and yoga studio owner who won the Democratic nomination Tuesday. The district, which includes Charleston and the southern coast, has not elected a Democrat since 1978.

Virginia: Trump supporter wins GOP Senate nomination

Polls have closed in Virginia's primary elections. Republican voters were picking a candidate Tuesday for the U.S. Senate while Democrats are choosing candidates in competitive House races.

Corey Stewart, an outspoken supporter of President Trump and Confederate monuments, won the GOP Senate nomination. Nick Freitas was backed by state party leaders.

Democratic U.S. Sen. Tim Kaine is seeking a second term, though he wasn't on a ballot Tuesday. The former governor and 2016 vice-presidential nominee became his party's nominee in March, when no other Democrats filed to run against him. So, unlike Republicans, Virginia Democrats did not need a primary Tuesday in the Senate race.

North Dakota: Kevin Cramer wins GOP Senate primary

U.S. Rep. Kevin Cramer has defeated a little-known opponent to win North Dakota's Republican primary for U.S. Senate.

Cramer easily beat Air Force veteran Thomas O'Neill on Tuesday. Cramer now faces a tougher campaign to unseat Democratic Sen. Heidi Heitkamp in a race seen as critical for control of the closely divided Senate.

Cramer is a former state Republican Party chairman. He was first elected to the House in 2012 and has easily won re-election twice since then.

Cramer initially passed up the Senate race this year but said he changed his mind at the urging of President Trump and others who saw him as the GOP's best hope to defeat Heitkamp.

The other notable statewide race was the GOP battle for the House seat Cramer is vacating.

Republican state Sen. Kelly Armstrong has won North Dakota's U.S. House primary. Armstrong is vying to replace Cramer.

Armstrong easily defeated former Marine Tiffany Abentroth and former North Dakota State football player Paul Schaffner.

State Sen. Tom Campbell also appeared on the ballot despite dropping out of the race. Armstrong, an attorney from Dickinson, has strong ties to the state's oil industry. He'll face Democrat Mac Schneider, a Grand Forks attorney who had no opposition in the primary. Schneider served two terms in the North Dakota Senate before being unseated in 2016.

Nevada: Trump-backed candidate wins congressional race

Danny Tarkanian has won the Republican primary for Nevada's 3rd District congressional seat left open by the incumbent Democrat who's running against GOP Sen. Dean Heller in November. The son of former UNLV basketball coach Jerry Tarkanian will face Las Vegas Democrat Susie Lee in the high stakes battle that is expected to be the most expensive congressional race in Nevada this fall. Lee clinched the Democratic nomination Tuesday.

Both candidates raised well over $1 million in their primary campaigns. Tarkanian didn't enter the House race until March when President Trump and others persuaded him to abandon an aggressive bid to knock off Heller in the Senate primary. The incumbent congresswoman, Jacky Rosen, won the Democratic Senate nomination Tuesday for the right to challenge Heller in November.

Steve Sisolak, a Nevada politician backed by former Sen. Harry Reid, has won a contentious Democratic primary for Nevada governor. Sisolak, chairman of the Clark County Commission, bested his commission colleague Christina Giunchigliani and four other candidates on Tuesday.

Sisolak outraised and outspent Giunchigliani in the race and earned backing from former Nevada Democratic Sen. Harry Reid. He's expected to face Republican state Treasurer Adam Laxalt in the November election.

Sisolak has spent a decade on the governing body for Clark County, which includes the Las Vegas Strip and about two-thirds of the state's residents. Nevada hasn't had a Democratic governor in two decades. Moderate Republican Gov. Brian Sandoval is leaving the office because he is term-limited.

Democrat Steven Horsford has won the Democratic primary for the 4th District congressional seat he held in southern Nevada for one term before Republican Cresent Hardy defeated him in 2014. He'll face a rematch in November against Hardy, who captured the GOP nomination Tuesday night in the swing district that stretches from north of Las Vegas through four rural counties.

Incumbent Democratic Rep. Ruben Kihuen announced earlier this year he would not seek re-election to a second term amid allegations of sexual misconduct. Horsford became the first African-American to represent Nevada in Congress when he was elected in 2012. He beat five other Democrats in the Tuesday's primary, including state Sen. Patricia Spearman.

Nevada voters were deciding a competitive Democratic primary race for governor Tuesday, a contest that became the state's most closely watched after President Trump helped clear a path to the GOP nomination for vulnerable Sen. Dean Heller.

Heller, the only GOP senator seeking re-election in a state won by Democrat Hillary Clinton in 2016, was originally expected to face a tough challenge from Republican Danny Tarkanian until Mr. Trump asked him to run for Congress instead.

Heller now can expect to breeze through his primary and focus on a November battle with Rep. Jacky Rosen, who is expected to easily win her party's backing against five others.

The toughest choice for Democrats was a close battle between Clark County Commission colleagues Steve Sisolak and Christina Giunchigliani -- each hoping to be Nevada's first Democratic governor in two decades.

Two longtime Democratic voters in Sparks, both 67, parted ways on the race.Medical technician Pamela Jones said she voted for Sisolak because he seemed more honest. Retired AT&T worker Debora Lee said she went for Giunchigliani because she liked her record in the state legislature.Both candidates have pledged to stand up to Mr. Trump and the National Rifle Association.

Sisolak, 64, is chair of the powerful governing body for Clark County, which includes the Las Vegas Strip and about two-thirds of the state's residents.But Giunchigliani paints Sisolak as too moderate and has knocked him for receiving an "A-" minus rating from the National Rifle Association in 2012.

Giunchigliani, who goes by "Chris G," is a 63-year-old former state legislator and teacher. She's earned backing from the women's group Emily's List and on Sunday picked up an endorsement from Hillary Clinton.

Interest in the race pushed voter turnout by Tuesday afternoon to a higher level than the 2016 Nevada primary, according to Nevada Deputy Secretary of State for Elections Wayne Thorley.

The winner of the Democratic race is expected to face Republican state Attorney General Adam Laxalt in November. He's a former lieutenant in the U.S. Navy, the grandson of former U.S. Sen. and Nevada Gov. Paul Laxalt and son of former U.S. Sen. Pete Domenici of New Mexico.

Laxalt, who is expected to win the GOP primary, was endorsed Tuesday by Trump.Wes Elliott, 70, said he voted for Laxalt because he likes the candidate's character and the fact he's a military veteran.Another key Trump supporter, Tarkanian, is favored in the Republican race for Nevada's 3rd Congressional District. It is one of two swing seats in Nevada that Democrats are hoping to hold while they make gains elsewhere to win control of the U.S. House.

Tarkanian, the son of former University of Nevada Las Vegas basketball coach Jerry Tarkanian, has run unsuccessfully for several offices over the past decade.He is in a nine-way primary. If he prevails, he's expected to advance to a general election against wealthy Democratic philanthropist Susie Lee. She faces six opponents in her primary.

The most serious primary challenge to an incumbent member of Nevada's congressional delegation is conservative activist Sharron Angle's bid for Nevada's 2nd Congressional District.

Angle is a former legislator who gained national attention in 2010 when she unsuccessfully challenged ex-Senate Majority Leader Harry Reid. She has faced criticism for statements on guns, immigration and other issues. Incumbent Rep. Mark Amodei is favored in their race. Amodei has been in office since 2011 and represents a conservative northern Nevada district.Voters on Tuesday were also deciding inter-party races for lieutenant governor, secretary of state, treasurer and attorney general. They'll narrow the field in nonpartisan runoff races for the state Supreme Court and Clark County sheriff. Voters will settle about 30 primary battles for state legislative seats.

One of those races in Nye County pits incumbent Assembly member James Oscarson of Pahrump against Nevada's most famous pimp, Dennis Hof.

Hof, who starred in the HBO adult reality series "Cathouse," owns half a dozen brothels that could be threatened this year under proposals to ban such businesses in two of the state's seven counties where they're legally operating.

Hof has said the proposed brothel bans are a political attack tied to Oscarson, something Oscarson has denied.

Maine: Democrats eye Polquin's seat

History is being made in slow motion in Maine where ranked-choice voting faces its biggest test yet. Democrats and Republicans ranked candidates for governor from first to last in Tuesday's primaries in a system that's sometimes called "instant runoff" voting in 11 local jurisdictions where it's currently in use. But there's nothing instant about Maine's process.

If there's no majority winner, then the ballots will be shipped to Augusta for additional tabulations. Under the system, last place candidates are eliminated and votes reallocated until there's a majority winner.

If it comes down to that, then Secretary of State Matt Dunlap said winners won't be announced until sometime next week. Mainers who approved the system in 2016 also voted Tuesday on whether to use the system in November for federal races.

Voters in a central Maine city have decided not to recall a mayor who came under criticism after using social media to tell one of the survivors of a Florida school shooting to "Eat it."

Waterville Mayor Nick Isgro faced the recall vote on Tuesday. He directed the April tweet at David Hogg, one of the survivors of a shooting that killed 17 students at a Parkland, Florida, high school. Hogg is an advocate for strengthening gun laws.

Isgro was tweeting in response to a Fox News decision to stand behind pro-gun rights commentator Laura Ingraham in the wake of an advertiser boycott. Isgro has made the case that the failed recall attempt was actually an effort to get him out of office so he can't veto the city's budget. City Manager Michael Roy has disputed that claim.
