Just poll the guys on this site who have said that they would vote for any Republican others than Trump. This site is heavily Republican, and Trump wouldn't win here.
If the midterms didn't tell you anything, it showed that Trump still can't win in the swing states. He cannot win a National election without Pennsylvania for example and his selected candidate, who he supported got beaten by a guy who literally couldn't talk. Let that sink in for a second.
What you guys don't seem to understand is that I and many others will never vote for Donald Trump. I don't like Biden, but I will vote for Biden before I ever vote for Donald Trump. You also don't seem to understand that much of the country doesn't see the Biden tears as a "shit show". Many understand that coming out of a historic economic shut down, there was going to be some challenges.
As I keep saying, a vote for Trump is a vote for Joe Biden. You also seem to underestimate Donald Trump's complete inability to shut his mouth. The more he talks, the more unlikeable he is, and he seems completely dedicated to pushing to the right. That will make guys like you happy, but completely turn off the people he needs to win over to get elected.
