If Romney-R wins, Manchin(D-WV) might be the Zell Miller of the 2010s.
During the Bush v Gore race. Bush carried GA by a double digit margin and Miller remained neutral.
During the Bush v Kerry race. Bush increased his margin of victory in GA and and Miller went of the deep end.
Manchin could endorse Romney-R in his 2016 re-election campaign, give keynote address at RNC convention and go on Hardball and challenge Chris Matthews to a duel.
So basically, if Romney wins MSNBC features live duels to the death? That's not a bad idea; it'd certainly boost ratings, especially among the WWE crowd...
