I've spent a fair amount of time listening to Trump and Harris.
Trump seems bombastic at worst. Harris seems like an idiot at best.
And when I watch or listen to legacy news media, I hear stories about each that has nothing to do with what I've seen/heard of each with my own eyes/ears.
Whoever owns those legacy news media companies clearly believe an idiot is better for their earnings/profits.
I'm pretty sure explanations more complicated than that are somewhere between unnecessary and bullshit.
