Art Laffer voted for Clinton and Obama. His own admission. Art may be a lot of things but conservative probably isn’t one of them.
Also none of the conservatives on your list ever ran for office. You need to compare Lauren Boebert to Congressmen, and compared to John Schmitz (R-CA) she isn’t exceptional.
In retrospect, Clinton was more pro-business than Bush1. Also, Laffer returned to Republicans, advising the Trump administration:
The point is that conservatives have become anti-intellectual compared to how we were in the 20th century, and we seem to be taking cues now from idiots like this woman.
