The Electoral College has affirmed Donald J. Trump as the nation’s 45th president, pushing him past the 270-vote threshold for election, with scant evidence of the anti-Trump revolt among electors that some of his critics had hoped would occur.
Normally a political footnote, the electoral vote took on unexpected import this winter after Mr. Trump’s upset of Hillary Clinton, who won the popular vote, spawned a determined effort to block his path to the presidency by grass-roots advocates who saw him as unfit for the White House and, to some, a threat to the political system.
Presidential electors and particularly Republican electors, who are bound by tradition and often state law to support Mr. Trump were inundated with phone calls, emails and even threats demanding that they vote for someone else.
Leaders of groups that were lobbying the electors had privately believed they had a chance to persuade enough Republican electors to defect, denying him an Electoral College majority and throwing the election to the House of Representatives.
But by late Monday, only a handful of electors had broken ranks.
