That's not really the point, though. Elections for federal offices are run by the states. The Trumpers can complain all they want about voter fraud and vote manipulation, but if the evidence isn't there (which it almost certainly won't be), then it will be a fair and free election.
Obviously I would prefer if these morons on the right wouldn't fall for Trump's conspiracy bullshit, as democracy functions much better when everyone has faith in the integrity of elections. But as long as the elections are fair, that's still something in the "plus" column.
