Is there a requirement to send the election of the U.S. president and vice-president to the House if no candidate gets a majority on the first ballot or can the Electoral College have multiple ballots before announcing a deadlock? Has this ever happened?
I found in wikipedia that this is an invalid question. I had been under the impression that the Electoral College got together and voted. I now see that each electoral college member sends his ballot to Congress to be certified so there is no possibility of multiple rounds of balloting.
The Electoral College never actually meets as one body. Electors chosen on Election Day meet in their respective state capitals (electors for the District of Columbia meet within the District) on the Monday after the second Wednesday in December, at which time they cast their electoral votes on separate ballots for president and vice president.
The U. S. Electoral college does not use multiple ballots. If a majority is not reached in the only ballot round, the president is chosen by the House of Representatives, with one vote per state's congressional delegation (i.e., 50 votes total instead of 435). See the Twelfth Amendment.
This has occurred twice, when Thomas Jefferson and John Quincy Adams were chosen as president.
