No no no, he is a lot of things, but stupid is not one of them.
There is something happening in the Democrat party that is causing Schumer to do this no matter how bad it is for what ever reason.
Maybe Watergate 2 x 1000 is about to explode and Chuck knows it.
Schumer IQ is among the higher ones out there, his ethics are shit, but the man is not dumb.
Intelligence often has no bearing on whether or not someone acts like a fool. It’s a question of judgment and whether one can control their ego and baser instincts. I see little evidence that Schumer is a skilled player, especially if he stupidly carries their filibuster through and forces the Republicans to change the senate rule.
If he’s allowing others in the party to cause him to act so stupidly on several occasions, then he’s not much of a leader.
