I don’t think so. The Republican Party had some pretty consistent positions for the better part of the last century, until those got in the way during the Obama era. It’s not like it was perfect before but when it came to questions like “is the President above the law?” or “is Canada an ally?” you could predict how most of the party would side. Stuff like granting unappointed people control over multiple agencies, running roughshod over the national security process, trying to impound huge chunks of the budget, etc. wouldn’t have flown even in Trump’s first term before they finished purging non-loyalists from the party.
