The Election: Full Guide – The New York Times

In one last push to win Pennsylvania, where early voting has lagged, the former vice president will make Election Day stops in Scranton, where he was born, and Philadelphia, where Black turnout four years ago was lower than forecast. Mr. Biden is expected to deliver remarks sometime late Tuesday night or Wednesday morning from Wilmington, Del., but if the result remains in flux he may wait.

It’s unclear what Mr. Biden would do if Mr. Trump declared himself the winner before there was clarity in enough states to accrue the necessary 270 electoral votes. Mr. Biden, after a campaign premised largely on the idea of returning to presidential norms, would be stepping far out of character if he too called himself the winner before results were known in enough states.

If he wins, Mr. Biden will be at a major inflection point for his party whenever he finally speaks before a national television audience. Having built a diverse coalition held together mainly by its antipathy toward Mr. Trump, Mr. Biden’s first moves as president-elect will provide distinct clues about what sort of presidency he hopes to lead — and how he may navigate what could be the most contentious presidential transition since 1876, when Rutherford B. Hayes and Samuel Tilden disputed the result of the election up until two days before the inauguration.

Control of the Senate is also among the biggest issues being decided Tuesday, with the result going a long way toward determining the contours of the federal government for at least the next two years.

If Mr. Biden wins the presidency, Democrats need to flip a net of three Senate seats to take control of the chamber; if Mr. Trump is re-elected, they will need four.

There are 12 competitive Republican-held seats; two Senate Democrats have competitive races.

The biggest prize is Georgia, where Senators David Perdue and Kelly Loeffler both face stern tests from the Democratic challengers Jon Ossoff and the Rev. Raphael Warnock (Ms. Loeffler also faces a challenge from the Republican Representative Doug Collins, in a special all-in primary). The state requires a winner to get at least 50 percent of the vote, or else either contest (or both) will be decided in a runoff in January.

Polling suggests Democrats are favored to pick up seats held by Senators Cory Gardner of Colorado and Martha McSally of Arizona, and lose the one held by Senator Doug Jones of Alabama.
