With Chief Justice John Roberts joining the court's three liberals, the court split 4-4 to reject a request from Pennsylvania Republicans to block an order from the state's Supreme Court allowing mail-in ballots to be counted if they are received within three days of Election Day — even if they do not have a clear postmark. The tie left the state decision in place, which Democratic lawyers hailed as "great news for voting rights."

President Donald Trump has a lot of options available to him when it comes to his attempt to steal the election. That doesn't mean they'll work, however.

In an interview with Democratic "super-lawyer" Bob Bauer, "The Circus's" John Heilemann listed a few scenarios for Trump trying to steal the election.

"We already have an electoral infrastructure -- a voting system -- that is not always adequately resourced or supported," Bauer explained. "You take that system, you layer on top of it a pandemic, you lay on top of that destructive behavior by one of the major political parties who espouses this kind of nonsense, and you add on top of that the internet-distributed misinformation plays, and that just means that the task that you have to address these contingencies is much larger than it's been as a structural matter any time in the past."
