Trump has gotten a lot of bad press lately, but it doesn't seem to have affected his polling numbers, which still show he will likely win.
However, I also get the impression that Trump's supporters are far less enthusiastic than they were 4 years ago, apart from his die-hard "base". For example, I can recall driving through Southern Delaware 4 years ago and seeing how every house having a flagpole had replaced the Stars and Stripes with a Trump flag. This year, not so much. Elsewhere, I see a lot less overt support for Trump. I have seen no lawn signs in my overwhelmingly white neighborhood, whereas I've even seen 1 or 2 Harris signs. I saw voters being interviewed at a state fair on TV. All white people said they'd vote for Trump, but most seemed to be settling for him given the only other major candidate is Harris. They don't admire him in the least. Christians admit he's not a Christian, but at least he's not Harris. I don't think you would have seen that in 2020.
Consider that polls in 2016 showed that Hillary would win. But respondents indicating a preference for Hillary had no real enthusiasm for her. Believe it or not, some voters are actually enthusiastic about Harris, especially some women. Hillary didn't have enthusiasm from anyone.
So I can see a chance Trump could win, despite poll results.
