Yeah, it's not hate. It's frustration mostly, because he clearly has dementia, which puts our country at a disadvantage politically, militarily, etc., on the world stage. His handlers must pump him full of something when he needs to be "on" (for example, the debates and even then he was not all that good) because the next day he's practically a gibbering vegetable. Well, more so than usual. And in my case, I'll admit to some anger that the DMC and the media, etc., would use him, when he clearly should be sitting on a porch somewhere, sipping lemonade, and with his great grandchildren bouncing on his knee. Although if I were a parent in that family, I'd make sure somebody was always there with him when the kids are around, if you know what I mean!
As far as Dementia Joe himself, I've never liked him politically. Neither did the American public, since they rejected him as a POTUS candidate multiple times (mostly due to his outright lying about his background and accomplishments.) That was the case right up until the last election when the DMC fixed the South Carolina primary, so that the party would latch on to him as the only hope to beat Trump. As for the general election, no comment.
