Like it or not, it sanitizes the victory of a brutal cheat and legitimizes him. If the VP doesn’t take the bait by upholding one or more objections to state electoral tallies, it’s game over. Try again in another 4 years. You’ve been skunkitinoed!

This kind of stuff happened before and resulted in Bleeding Kansas.
