Bizarre question. They've never distanced themselves from him. It's been Trump's party for six years give or take.
OK, here are some questions for the cheap seats-
How many members in the Republican Party?
How many are associated with MAGA?
How many mainstream Republicans are interested in being polluted by the MAGA members?
How many Republicans are close to the center and don't want anything to do with the extremes?
Make a Venn diagram if you have to- maybe then, you'll see that not all Republicans are the same.
You use "they" as if you know how they all think.
