All they're able to do is stick their heads in the sand and lie out their rear ends. There's no legitimate way to justify attacking Biden on any of the metrics they use because every single time Trump is worse.
It's noted that none of them can address any of the verbal diarhea from Trump®. I personally agree Biden is less sharp than he once was, but the senile thing is WAY overblown. He's always been a gaffe machine, he is old as dirt, but being a recovered stutterer explains a lot I was unaware of until this election. I'm not at all thrilled about Biden, or very hopeful he can fix the disaster that has been Trump®'s complete lack of doing anything.
These asshats actually BELIEVE, that Trump® has "run the couuntry". It's CRYSTAL CLEAR. Pence and the administration has done the job, and are basically Trump®'s babysitters and "handlers", because EVERYONE in their right mind knows Trump® has lost his mind. It's a MARKED decline from Trump® of the 80s; side by side videos are SHOCKING! They (the rest of the cabinet) have only not exercised the 25th on him, not out of confidence in him, but in KNOWING, that should Trump®, go down, they all fall behind him, he doesn't care. They can barely control the fool, but they KNOW if they defy him he will take them all out, mercilessly, just because it's who he is, it's ALL he is, sadly....
I mean we could post some of the side by sides of Trump, back when he was a relatively sane sociopath, compared to now, but why? Those folks love him on an emotional level, that nothing but confirmation bias exists....
That's the only other reason for not dumping Trump for Pence. If they could safely dump the moron, I've no doubt they would, but if they did, they lose the cult of personality of Trump® and replace it with the robot, sand personality programming that is Mike Pence. That is GREAT on Policy for the GOP, but it won't win any national election, ever, and they know that....
