"Discarding the votes of a decisive state would leave neither candidate with the 270 electoral votes needed to win a majority. (That’s what would have happened had Congress rejected Florida’s electoral votes in 2000). If no candidate won an electoral majority, the election would be thrown into the House of Representatives, where each state—not each member of Congress—would cast one vote. Right now, even though Republicans have only a minority of House members, they have a majority of state delegations. And in this scenario, Wyoming’s lone House member would have the same clout as California’s 55 members. If that holds true after November 2020, House Republicans might possess the power to give Trump a second term."
