It's officially the day after Election Day and the country, and world, are waking up without knowing who the next president of the United States will be.

It was expected we wouldn't know who the victor was Tuesday night.

What's going on in Pennsylvania?

Pennsylvania is waking up Wednesday without a winner, as its 20 electoral votes are poised to play a decisive role in a close presidential race.

Republican President Donald Trump is leading Democratic challenger Joe Biden 55%-43% in the Keystone State, but that could change after more than 1.4 million outstanding mail-in votes are counted.

Those mail-in votes are expected to heavily favor Biden because more Democrats voted by mail, while more Republicans voted in person. Also, the mail-in votes are largely uncounted in counties won by 2016 Democratic nominee Hillary Clinton: Philadelphia, Allegheny, Chester, Bucks, Delaware and Montgomery.

Biden holds narrow lead in Nevada, more results expected until Thursday

Democratic presidential nominee Joe Biden held a narrow lead in Nevada as of Wednesday morning as the Nevada Secretary of State said it would not release any more results until Thursday.

The Secretary of State's office said in a Twitter post they had already counted all in-person early and Election Day votes, and mail ballots sent through Nov. 2. The state still had yet to count all of the mail ballots received on and after Election Day, as well as provisional ballots.

Nevada was one of several states that mailed all registered voters a ballot this year, making it difficult to estimate how many ballots were still left to count.

The state's six electoral votes could be part of either candidate's remaining path to victory with several states still counting ballots. Biden held a roughly 8,000-vote lead with about two-thirds of the vote counted.

Where do things stand

Democratic nominee Joe Biden has secured the key battleground state of Arizona. It’s a state a Democratic presidential candidate has not won since Bill Clinton in 1996. Biden also picked up a win in Maine, with three of its four electoral votes (Maine is one of two states that doesn’t award all their electoral college votes to the statewide winner).

President Donald Trump secured wins in Texas, Florida, Ohio, Iowa, Montana, Idaho, Utah, Kansas, Missouri, Nebraska, Louisiana, Wyoming, North Dakota, South Dakota, Kentucky, West Virginia, Indiana, South Carolina, Oklahoma, Tennessee, Mississippi, Alabama and Arkansas.

Biden won Minnesota, Hawaii, California, Oregon, Washington, New Hampshire, Colorado, the District of Columbia, New Mexico, New York, Virginia, Vermont, Rhode Island, New Jersey, Massachusetts, Maryland, Illinois, Delaware and Connecticut.

That gives Biden 238 electoral college votes and Trump 213 after 3 a.m. EDT. A candidate needs 270 electoral college votes to win the election.

Biden camp slams Trump statement on outcome as 'outrageous'

A top aide to Democratic presidential nominee Joe Biden slammed President Donald Trump's premature declaration of victory early Wednesday and threatened to defend the counting of legally cast ballots in court.

"The president’s statement tonight about trying to shut down the counting of duly cast ballots was outrageous, unprecedented, and incorrect," Biden campaign manager Jen O’Malley Dillon said in a statement. "It was outrageous because it is a naked effort to take away the democratic rights of American citizens."

Trump falsely claimed during remarks at the White House early Wednesday that he had won the presidential contest, even though ballots were still being counting in several states that would actually determine the outcome, and he threatened to ask the U.S. Supreme Court to halt the counting of ballots he described as a "fraud."

Trump's remarks were consistent with his statements prior to the election in which he sought to cast doubt on the millions of absentee ballots cast this year because of the coronavirus pandemic. Those mail ballots always take time to count – sometimes several days. This year, there's simply more of them to count.

Polls taken before the election indicated that Democrats were far more likely to vote by mail and Republicans were more apt to vote in person.

"We repeat what the Vice President said tonight: Donald Trump does not decide the outcome of this election. Joe Biden does not decide the outcome of this election," O’Malley Dillon said in a statement. "The American people decide the outcome of this election. And the democratic process must and will continue until its conclusion."

Biden and Trump express confidence

Democratic nominee Joe Biden addressed supporters late Tuesday night, saying he felt he was "on track" to win the election because of support from mail-in votes, while urging supporters to exercise patience while states count ballots.

"We feel good about where we are," Biden said. "We really do."

Early Wednesday morning, Trump suggested – falsely – that he had already won, while million of ballots remained outstanding.

“Frankly, we did win this election,” Trump told supporters in the East Room of the White House. “As far as I’m concerned, we have already have won.”

Facebook and Twitter on early Wednesday warned social media users that Trump's claim is potentially misleading.

Dems losing chance to flip the Senate

The chances of Democrats flipping enough seats to take control of the Senate appeared to be dwindling early Wednesday as Republicans fended off challenges in a number of key races. You can track those results here.

You can also stay updated on control over the House of Representatives here as Democrats are projected to retain control but have been underperforming.

Battleground states up for grabs

A number of battleground states are still on the table as of 3 a.m. EDT, but a few crucial ones have been called.

Trump held on to some crucial battleground states he needed for a road to reelection, including Ohio, Texas, Florida, and Iowa.

However, Democratic nominee Joe Biden made gains in Arizona and Nebraska's 2nd District, which rules out the possibility of a 269-269 electoral tie, while also keeping Minnesota and New Hampshire in the blue column.

The southern states of North Carolina and Georgia are too close to call, which, if either swing to Biden, would be gains from years past.

In Georgia, a few blue counties stopped counting ballots earlier in the night. One of those, Fulton County, which is home to Atlanta, had a pipe burst earlier Tuesday at State Farm Arena, which delayed the counting of absentee ballots. Democrats could pick up numbers there.

Key states of Michigan, Wisconsin and Pennsylvania are not expecting to know who the winner is until at earliest Wednesday morning, though some are predicting it could be a few days to accurately count all mail-in ballots.
