He is a creature of Washington who used his connections in the Senate to change votes and move his bosses agenda forward. Hes the only one of the bunch who isnt a complete noob. Granted, he’s awkward around normal people because he is used to people who are up to speed, and anyone who fell for Kamala’s bus story is not thinking about the unpopularity of the policy or the fact that she subsequently had to walk it back. It was a gotcha about what exactly? He is having problems code switching, but at least he has the code to switch.
Mentally, Biden is a step slow. It is a function of age. He hasn’t aged well. I say that advisedly being 76.
