I'd say it's far more dangerous to put an unscripted Trump in front of cameras as evidenced by his inability to talk about anything other than how the election was stolen from him, he's a victim of witch hunts and the most persecuted person in history...
That's probably why his polling numbers are so terrible.
Oh, wait...
In fact, the more idiotic things he says, the more they like him. I would have expected that to be obvious by now. The things he did on the campaign trail in 2016 were unforgivable, and he won comfortably. Why do you think things are going to change now?
Be aware that I have no dog in this fight - I'm able to look at it as a casual observer. You're quite right that people who should be supporting Biden are calling him senile, though. How do you think that's going to play out?
That was my point - he's winning and Biden's losing. In a sane world, Trump would be polling in single digits. He's not.
Smart move if you ask me. In a field of nutjobs, she's right at home.
FTFY
They aren't forgiving Trump's gaffes anymore than they 'forgive' his 3 marriages, grab 'em by the pussy, his being hell-bent on revenge or any other fault Trump has. They are in denial.
Denial/forgive, whichever you like.
The end result is the same - Biden is struggling to hold support and the orange toad is building towards victory. The polling numbers may well be inaccurate, but there's a trend of Trump increasing his support and Biden losing his. If that trend isn't reversed, Trump will win in a landslide.
It's already too late. Just as they hung their hopes on a certain loser in 2016, they're doing the same again.
