You could mostly just get rid of Nancy Pelosi and Chuck Schumer and most of the really bad stuff of late would be resolved. /s
I suspect that a lot of republican higher ups specifically avoided funding the border wall until they lost control of the house so they could manufacture this crisis (especially as the potential to fund the border wall was offered by democrats earlier and declined by republicans, and the senate passed a "just keep it open" bill before going on winter recess).
In all serious I don't know if this was meant as sarcasm but party cohesion in the republican party is quite high, it's one of the reasons the republican minority was effective against Obama - senators would freely discard logic to toe the party line.
