You don't understand that 2 things can be true at once?
It can be true that:
1) We needed Manchin's seat so that the GOP didn't control the Senate with a firm grip on Biden's balls
AND
2) The slim majority placed Manchin in a position where he had a grip on Biden's balls and half of his shaft
It's wild that libs think this is convincing. If Manchin, who is effectively just a blue republican going on Fox News and everything, is the ONLY way the party can maintain power, then maybe it shouldn't have that power.
