I saw Harris in person. She was perfectly cogent. I saw Trump during the debates. The bulk of his speech was non-sequiturs, half formed thoughts, simplistic summary’s of complex topics, or outright fabrications.
If you actually evaluated them on merit you know this.
What do the facts have to do with anything?

Conservatives have long since forgotten that Harris destroyed Donny in the one and only debate. Totally emasculated him, and his team knew better than to run it back again.
Besides, these false narratives are incredibly powerful to the electorate. It's perfectly inline with "Hillary is soooo corrupt!" and even (D) voters like our own BoomerD were parroting that Harris is un-intelligent. Who knows if people actually and truly believe this, or if it's just latent misogyny or racism at play. This is not a callout of BoomerD; he actually voted for Harris in spite of his personal opinions.
Having said that, my best buddy claims the #1 reason Harris lost is she's just not likable. Obviously misogyny and racism are real, but my buddy considered those secondary reasons. Not saying I agree with this ordering, but however you want to rank these 3 reasons, they do explain why many (D) voters stayed home in 2024 and gifted the presidency to a criminal. I've said many times Harris is not my pick in an open primary. I'm not even worried about Harris trying again in 2028, but I'd rather she doesn't take the California governorship.
