Will the Republican Party officially pivot to Trump's new populist/nativist ideology and pretty much abandon fiscal conservatism altogether?
The idea behind this theory being that Trump's approach will be deemed the path more connected to Republican voters.
No. There are very few people in power in the GOP who subscribe to his ideology. It's dependent upon a charismatic strongman like Trump, and few politicians have the gumption to be that audacious. Without Trump, there's no Trumpism.
The TEA Party wing will try to court the Trump voters, however. If they are successful, it may drive some GOP members of Congress to switch parties. I have a feeling that's going to happen anyway.
