I think the Democrats will collapse. Voter fraud is still a concern, but hopefully that can be mitigated.
If they embarrass themselves and if the public sees that their approach to politics has been soundly rejected, then draining the swamp gets a lot easier. I had hoped that would be a First term goal but now it looks like it is (maybe) a Second term goal.
You hit the nail on the head when you said voter fraud is still a concern. But until the republican side grows a set voter fraud will always be there.
