If MAGA wanes, could the Tea Party make a comeback? Or is the latter squarely an Obama era opposition movement. I just don’t know how Ted Cruz, Scott Walker, Marco Rubio (well he’s been rebranding himself as more of a Catholic common good type), and others of their ilk will call themselves. There will still be plenty of small government types in the GOP who don’t care about protectionism and leave immigration as a secondary concern.
The Senate GOP seems to think we are on the verge of a Tea Party comeback, but I don't necessarily think so at this point.
Even if there is a populist wave or discontent, I don't think it is going to be exactly like the Tea Party and will almost certainly contain a much more populist element.
They're being incredibly idiotic if they think there is literally going to be a Tea Party 2.0 where spending/taxes is the focal point.
If anything, the coming GOP backlash will be even more racially and culturally animated than the Tea Party was. And it will be happening with a president who's an old white Irish Catholic guy who is quite literally a throwback to the earlier America these people keep insisting they want to restore.
