It really takes both to get anything done. Controlling the Congress w/o the WH is rather pointless unless you have enough leverage over the WH to extort things through. And as you point out, the GOP controlling is not all that different than the donkeys at the end of the day. Swamp is gonna swamp. Even when GOP had both houses in Trump's first 2 years, they worked nearly hand in hand with the donkeys to cut him off at the knees. There is no reason why the southern border wall could not have have been largely completed in this time had the GOP bothered to support it. Once Fancy Nancy got her gavel back it was "come on in". Even the false Messiah managed to blow up the health care system in his first 2 years.

What D.C. needs is a full on Heracleaseian Augean Stables cleaning to flush out all the shit.
