There simply won’t be another election.

That is a possibility. The US elected fascists who now control all three branches of the federal government. However they do not have a two-thirds majority in congress or control two-thirds of the states. So it will be difficult for the fascists if they choose a purely legal route. However, since they are fascists, they might use violence to get what they want. We won’t know until they try.

In the event that we still have elections and Democrats can still participate we should leverage power and vote for Democrats in those elections. This will reduce the harm done to minorities by fascists who want to kill them.

I wanted to add to your point, because people in this comment section are attempting to write off future elections unless Democrats completely meet the demands of progressives. This isn’t something Democrats are likely to do. But the people who will be harmed by hypothetical future Republican administrations would prefer if Democrats were clogging up the works and knocking fascists out of power at the very least.
