Thinking Trump can't win again is dangerous. He very much can.
He can win. But I don't think he will. As long as we put up a candidate who's more than 'not trump'.
So Trump winning again is basically a certainty then.
While I think democrats have a good chance, there is a few people in this topic who cannot look past what they want to see. Hell, you got people in here acting like a pro-corporation ruling is some human travesty. How many were touting generic ballot numbers and a blue wave and when the ballots are shrinking, they just ignore them and find a new way to support the way they think (4% now and shrinking).
The fact is too many in this specific topic are just so extreme in their views that they can't see the other side at all.
I was pretty pessimistic about Trump's odds initially, but I more and more I think his re-election is likelier if the economy keeps moving in the direction it has been and barring an unmitigated disaster.
