You’re right its all anti-Trumpian theater!
Which unfortunately does have a positive effect (in the anti-trump way!) on some voters.
We got rid of a lot of Never Trump idiots last night
We flushed a lot of turds out of our own party
And made headway with the senate +4 or 5 is a big win for us
Dimms have a small razor thin majority in the house, not every single one is a mouth breathing leftist idiot, some are moderates and a small few might even be somewhat conservative (for a democrat). Those people will run the house and the agenda. Just like Collins and Rand Paul did in the senate in a way. But we will see
We might get a wall (or a big start on it) after all. Remember the moderate dims in republican areas want to get re-elected in 2020.
