回复15楼:The 12th Amendment of the Constitution lays it out:
“The president of the Senate shall, in the presence of the Senate and House of Representatives, open all the certificates, and the votes shall then be counted,” it reads.
So Pence will oversee the joint session of Congress, opening each of the certificates of each state's electoral votes and then presenting those to already appointed House and Senate "tellers" in alphabetical order.
"The person having the greatest number of votes shall be president," the amendment continues.
