I will grant that passing tax reform would be a net positive for republicans heading into 2018, but it's not because tax reform represents Trumpism, but instead because tax reform has energized republicans for decades. Same goes for making ObamaCare more conservative - republicans have hated health care reform since the days of HillaryCare.
If Republicans pass a Bush style tax cut, then Nancy Pelosi really will be Speaker. And next Republican Speaker will likely be a economically moderate populist 10 years or 15 years from now, who was a big Trump supporter in 2016 and has found out how to adapt that message into a mainstream one.
But Bushism, Neoconservativism and Movement Conservatism as we have known it, will be well on the sunny side of dead.
Honestly, it just feels like you are pushing for your desired type of GOP.
Some liberal once said something like "if you hate the religious right, just wait until you see the non-religious right". That's basically what Trumpism is, and I really want to go back!
It wasn’t a liberal that said that.
