Joseph Robinette Biden Jr. was elected the 46th president of the United States on Saturday, promising to restore political normalcy and a spirit of national unity to confront raging health and economic crises, and making Donald J. Trump a one-term president after four years of tumult in the White House.
Mr. Biden’s victory amounted to a repudiation of Mr. Trump by millions of voters exhausted with his divisive conduct and chaotic administration, and was delivered by an unlikely alliance of women, people of color, old and young voters and a sliver of disaffected Republicans. Mr. Trump is the first incumbent to lose re-election in more than a quarter-century.
The result also provided a history-making moment for Mr. Biden’s running mate, Senator Kamala Harris of California, who will become the first woman to serve as vice president.
With his triumph, Mr. Biden, who turns 78 later this month, fulfilled his decades-long ambition in his third bid for the White House, becoming the oldest person elected president. A pillar of Washington who was first elected amid the Watergate scandal, and who prefers political consensus over combat, Mr. Biden will lead a nation and a Democratic Party that have become far more ideological since his arrival in the capital in 1973.

Today, former  Joe Biden was projected by multiple media outlets to have surpassed 270  delegate total and therefore become the 46th President of the United States elect.

His running mate, Kamala Harris, would become the first female and first African- and Asian-American vice president.  

At around 11:25am  (1625 ), the Associated Press (AP) called the election for Biden, as did NBC News, when Biden was declared to have won Pennsylvania's 20 electoral college votes. Later in the day, the AP and NBC News also called Nevada for Biden, giving him an additional six electoral college votes, for a total by NBC's reckoning of 279 electoral votes to President Donald Trump's 214, or 290 electoral votes by AP's reckoning.

Biden said in a statement, "I am honored and humbled by the trust the American people have placed in me and in Vice President-elect Harris". He added, "With the campaign over, it's time to put the anger and the harsh rhetoric behind us and come together as a nation. It's time for America to unite. And to heal ... We are the United States of America. And there's nothing we can't do, if we do it together."

President Trump has yet to concede, saying earlier in the morning before the call for Biden, "I WON THIS ELECTION, BY A LOT!" on Twitter. Following the announcement of Biden's win, Trump issued a statement at  outside Washington, D.C. saying, "The simple fact is this election is far from over. Joe Biden has not been certified as the winner of any states, let alone any of the highly contested states headed for mandatory recounts, or states where our campaign has valid and legitimate legal challenges that could determine the ultimate victor". The lack of a concession from Trump has no legal standing.
