Biden eats into Trump's lead in Pennsylvania, which is now at 18k votes

As news hit early Friday that former Vice President Joe Biden has edged ahead of President Donald Trump in the ongoing fight for Georgia's 16 electoral votes, Trump's lead in Pennsylvania, a state he must win, is dwindling.

The president is on top by about 18,000 votes in the sought-after swing state, with about 3% of mail-in votes still to be counted.

Without Pennsylvania's 20 electoral votes Trump has no path to the presidency.

Less than 24 hours ago, Trump led in the Keystone State by more than a 100,000 votes. On Wednesday, his lead in Pennsylvania surpassed 600,000.

Many of the mail-in ballots being counted are from Philadelphia and its suburbs, areas that heavily tilt toward Democrats.

Trump has so far prevailed in a legal challenge he brought in Pennsylvania that mandates that election observers be allowed to observe the count within six feet of any table or area where the counting is taking place. Poll watchers were initially required to remain at least 25 feet away from these areas, a distance Trump's campaign team objected to.

Trump has so far failed in a separate legal bid to get the count in Pennsylvania halted altogether.

Biden takes the lead from Trump in Georgia

Democratic candidate Joe Biden officially took the lead in Georgia Friday, after a new round of results were released.

As of 4:30 a.m. EST, the former Vice President leads by 917 votes with thousands of ballots remaining to be counted.

Biden caught then passed Trump in the traditionally red state due to an onslaught of mail-in ballots from Democratic-leaning counties. Democratic voters utilized early voting and mail-in ballots across the nation more so than Republicans.

Georgia is critical to Trump’s reelection, but not necessary to Biden’s path to the White House.

The state has not backed a Democratic presidential candidate since 1992, when Bill Clinton won the state by 13,000 votes. Trump beat Former Secretary of State Hillary Clinton in Georgia in 2016 by 211,141 votes, or 50.4% to 45.3%.

Clayton County, which was represented by the late Rep. John Lewis, was one of the counties that put Biden over the top in Georgia.

Could today be the day?

No states were called Thursday in the presidential election, but Friday may well be the day the election ends when most of the remaining battleground states hit the home stretch in counting and even call some races.

Biden begins the day with 264 Electoral College votes to Trump's 214. That means Biden needs to win one of the four remaining battleground states. All of them are expected to make significant progress or finish counting outright.

One of those critical states is Georgia, where Democratic nominee Joe Biden took the lead Friday morning as voting continues.

In Pennsylvania, major counties such as Philadelphia have been counting through the night, and the president's lead there is also narrowing.

Biden gained ground due to an onslaught of mail-in ballots from Democratic-leaning counties.

Arizona and Nevada finishing up

Voters can also expect updated results Thursday morning from Arizona, where Trump has been narrowing Biden's lead, and Nevada, where Biden leads by around 11,500 votes.

An estimated 190,150 ballots remained uncounted in Nevada on Thursday, according to the Reno Gazette Journal, which is part of the USA TODAY Network.

State elections officials announced nearly two-thirds of that total were either returned by mail or dropped off in-person on Election Day. The remaining 66,596 votes were cast by same-day registrants either in-person on Tuesday or during the state's two-week early voting period.

Some 90% of the outstanding ballots are in Clark County, a southern Nevada stronghold for Democrats where the party built up a daunting 89,000-voter edge over Republicans in early voting turnout.
