I really can't imagine any timeline where Vance is popular. Even republicans think he's a fat dumb baby. He has less support from Republicans than Hillary had from democrats, which is a pretty stark departure from their usual fall in line behavior. Either way, as I stated, if they knew they weren't bulletproof it might put a little more caution in their step. For all we know, the attempt's on Trump's life and the protests in DC and other cities are what has kept Trump and the SCOTUS from pulling a complete coup.
