Continuing Our Series about the Electoral College: Where Do the Electors Meet? “The meetings are held at the state capitols and in the District of Columbia. They start around 9 a.m. and end around 3 p.m. in various states. The electors cast their votes and sign a form confirming they voted. That all goes into the Certificate of Vote. Once those documents go to the federal government, the Office of the Federal Register confirms the votes and then they are read out in Congress in early January. There is a process for House and Senate members to object to votes, but that is rarely used and hasn’t affected an election.”
