The bigger part, amongst other things, Harris is part of the current administration, people are not happy about how things are going, or how much their groceries cost. People are not happy to get censored or called nazi's for having different opinions. When asked on a left-leaning show "The View" with people all on her side, what she would change about the last 4 years, she answered, "there is not a thing that comes to mind".
Charisma didn't kill her, not being able to ask layup questions killed her. The American people are not as dumb as the Harris voters are now screaming about on Reddit/TikTok/X, the American people want to know what their president is going to do to change their lives. Trump is a sociopath, again amongst other things, but he is very very clear about where he stands on things and what he's planning on doing.
