They don't care.
Fetterman is not healthy enough to hold the office but the guy they installed as President isn't either. They are not aware of what the crack pot believes because .... it does not matter.
He is a means to an end, nothing else, another Senate Seat, power, all they need him do is raise his hand and vote Regime all the way.
From what I know of Fetterman, what he believes in, he is a fraud (a Democrat) The worst kind actually he has some "higher" degree from Harvard so he can claim to know things... he doesn't.
Even absent the stroke, if asked if I thought that guy was healthy or smart enough to hold public office, the answer would be a resounding no.
If I have not depressed you enough, he will win Philly and Pittsburgh, and that will most likely win the goon a Seat. All hail our Fascist regime.
Dr. Oz would be better choice but.... if we as a country cannot do better then these two, we are in fact doomed.
