"When I say moderate, I mean people like Romney or Sasse, who are quite conservative on policy but generally avoid white identity politics-style moves (attacking Black Lives Matter or immigration reform) and are full-throated in favor of democratic norms and values. Republicans who are moderate on policy, like Susan Collins and Larry Hogan, are basically nonexistent among top Republicans now."

I think this is that "Overton window" all the cool kids are talking about. If you don't want to overthrow the government, you're a moderate now.
