I do not think that the Electoral College tie would be an issue. It is not a vote in the House. It goes by state congressional delegation. In other words, each state gets one vote. All of the congressmen in a given state vote, and whoever gets the majority for that state gets that state’s one vote. You just have to win 26 states in that manner. I think the Republicans are safe in that scenario.
What happens in states where there is an even number of democrats and republicans?
