I'm not American, but the issue I saw time and time again from Americans getting interviewed by various news organizations was inflation, specifically food prices. So many people said that food was cheaper when Trump was president, so they want him and his food prices back. This is of course totally disregarding that the rest of the world also had massive inflation, and most of it comes from increased oil prices because of Russia's invasion of Ukraine, and governments printing money to use for Covid stimulus. The tariffs probably didn't help either, but I don't know how many of those Biden kept so I don't know if any side can be blamed there. I doubt all these new tariffs will help though.
I actually saw a couple people saying that they've received a check from Trump during Covid, and mentioned that as a clear reason to vote for him. I thought it sounded dumb when I saw that he insisted on having his name on the stimulus checks, but apparently it worked. I also saw some people, southern women and big city black men, saying that they definitely didn't want a female president. That was probably part of why Hillary lost, and making the same play this time wasn't very wise from the democrats, although I would probably blame Biden for not dropping out earlier and leaving them very little choice.
