Trump being senile doesn't matter to Trump voters. As long as he hates the same people they hate, they'll decorate their trailers and go out and put him in power.
Biden being senile did matter to Biden voters. That's why they attacked him on it. And rightly so. Let the poor man retire. It's not an easy job if you actually bother to do it.
The GOP won't replace Trump even if they his health does concern them, because if they do they go from just under half of the votes to being obliterated.
It's interesting that out of the republican base, there are that many more of "people who want a person [trump] who hates the same people they do" rather than "people who care about [traditional republican values]."
That they're running trump in the hopes to win means the party has traded its soul of traditional values for hate.
I have a theory that they'll tolerate anything to get into the whitehouse again, get proj 2025 rolling, then Vance et al do the ol 25th Amendment cha-cha and Peter Theil gets to control the white house.
By himself, Vance can't get Theil there, but riding the deranged tangerine palpatine into office is extremely plausible.
Right, in a sane world, Trump has been proving himself unfit to hold any more responsibility than a burger flipper for decades now. The fact that anyone could possibly be on the fence about him at this point means the game is already lost.
