Some were issue voters, where the issue was more important than all other considerations. You can't always get what you want. I vote Harris, not that I thought she would be a great president, but Trump was the issue I voted against. Some, maybe most, thought the economy, and for whatever reason thought him the best answer. I did not suffer economically. Some immigration the most critical reason, outweighing all other considerations, Trump the logical answer. Biden's damage to himself on that issue is undeniable. Still as single issue, not most significant to me, not living near the border, nor in a city or area with a massive influx of illegal aliens. Nobody in their right mind had any reason to believe Harris would solve this issue. I hold no pejorative illusions of why most Trump voters, voted Trump.
