You know it says something about the US conservative sphere, that they are constantly rebranding.
2000 - Bush style conservatism rebrands from toxic Gingrich Republican congress, with a somewhat bipartisan State Governor. 'Compassionate' moralistic conservatism.
2008-2010 - Bush and co are fully discredited, and he leaves office with approval in the low 20s. Republicans ignore Bush, concede somewhat that he was bad. Rebrand as hardline opposition to everything Obama does, and insane deficit hawks, despite spending like crazy during Bush years and some go Tea Party
2012 - Some conservatives in the aftermath of Bush, rebrand as Libertarians, Ron Paul 2012. They don't take over the party, but it becomes a useful label to hide behind for ashamed conservatives. Instead Mitt Romney wins the primary and loses the general. Also in the mix is the Paul Ryan types, who media proclaim as conservatives with ideas. Their one idea is tax cuts of course.
2014-2016 Trump takes over the Republican Party, now as a 'populist'. Very bad way to describe it, demoguague fits better. But he openly repudiates toxic Republican Paul Ryan economics, and doesn't both defending unpopular Republican missteps and trounces a Republican field. Most of the Paulite Libertarians become Trumpists.
2020-? Trump is very likely to lose with a campaign that has literally no ideas on anything, has reverted to Republican orthodoxy, and is full on cultural grievance politics. Lots of Republicans have already started visiting New Hampshire, preparing for the next primary, with candidates from all over the spectrum. My guess is a new morphing, and a new label of sorts.
