WASHINGTON (AP) - Electors are gathering Monday in every state to formally elect Donald Trump president even as anti-Trump forces try one last time to deny him the White House.

Hundreds of demonstrators are gathering on the steps of Pennsylvania's Capitol building with the faint hope that they'll persuade the electors not to vote for Republican President-elect Donald Trump.

The sign-waving protesters in 25-degree weather Monday were examples of demonstrations around the country against the Electoral College's expected selection of Trump as the nation's 45th president.

Clinton won the popular vote by 2.6 million votes but Trump is poised to win 306 of the 538 electoral votes under the state-by-state distribution of electors used to choose presidents since 1789.

Vermont's three members of the Electoral College are the first to report their vote for president. All three chose Democrat Hillary Clinton, reflecting the state's vote in the Nov. 8 presidential election. Clinton got 55.7 percent of the vote, while Trump received 29.8 percent.

South Dakota's electors are gathering at the state Capitol to cast the state's three Electoral College votes.

Gov. Dennis Daugaard, Attorney General Marty Jackley and state Republican Party Chairwoman Pam Roberts will cast their votes Monday in the governor's reception room.

Donald Trump carried South Dakota in the November election. Daugaard's chief of staff, Tony Venhuizen, says all three electors intend to support Trump.

Roberts is a substitute for Lt. Gov. Matt Michels. The lieutenant governor was chosen to be an elector but can't attend the event because of a scheduling conflict
