Vance is the least liked VP candidate in almost 50 years.
As a conservative I've not heard much if any positive reaction or excitement about JD. Although I'm not MAGA, so maybe if you get deeper into the that cesspool there's some excitement there, but even among the more MAGA friendly people I know, still, really not much about JD. Though it's not even negative reaction instead; it's just a collective shrug. If he's there as a pliable yes man who won't overshadow or buck Trump, mission accomplished. If he's actually supposed to help fire up the base or be an effective hatchet man against Harris... eh... not so far...
