After all, they have an enormous advantage in the Senate. There are more red states than blue.
The filibuster was never intended to work like it does now. It just wasn't. There were more bills filibustered in the Obama years than all previous presidents COMBINED.
It was never meant to be an instrument of obstruction. But it is now.
And just look at what is happening with Biden's nominees - Cruz is blocking ALL ambassadors and State Dept nominees, and Cotton was blocking ALL US Attorneys, the former over the Nordstream Pipeline and the latter (not exaggerating) because he was mad at Dick Durbin for interrupting him and not apologizing. For 8 months. Not kidding.
The Senate is dysfunctional.
