President Joe Biden's name will not appear on the ballot, but the stakes are high for the 81-year-old president and his legacy as he waits to see whether the US will next send his predecessor—Donald Trump—or his successor—Kamala Harris—to the White House, CNN reports.

The US president has been in the shadows in recent days and is expected to do the same today—on Election Day. Joe Biden and First Lady Jill Biden will follow the election results from the White House, along with longtime aides and senior White House staffers, a White House official said.

Biden, who has no public events on his schedule Tuesday, is expected to receive regular updates on the progress of elections around the country.

Today's election is a far cry from what Biden envisioned months ago, when he hoped voters would elect him to a second term in the White House, and the outcome could help determine how the US president is remembered.

Biden's team believes that his quick endorsement of Harris after he dropped out of the presidential race has helped the Democratic Party quickly rally around Harris' candidacy.

Harris' defeat, however, could raise questions within the party about whether Biden held on to the nomination too long, jeopardizing the Democrats' chances.
