So what would happen if there is an election dispute and then a 4-4 tie in the Supreme Court?

In that case whatever the appeals court (just below the Supreme court) decides will hold.

Riots would ensue. That is unacceptable and we need a full Supreme Court. Republicans need to push forward because of that.

[The Pack Knight]

Yes. Those 53 Trump nominees confirmed to the courts of appeals become pretty important.

I don't think it would go to an appeals court first. The Supremes can take it up without it going to an appeals court, and I think they would if it was an election-decider.
