If the Veep is the Congolese Hippopotamus from Georgia and Biden wins 40 states, then no, I'd guess some shenanigans were involved, and many will never support it.
If the Veep is Harris or Warren and they get 290-ish Electoral votes, I'd guess most will accept it. I would.
If the Senate flips in a huge way and perennial Red States all flip, you'd see serious resistance. If 2 battleground states flip, I think most would accept.
Just my guess.
