While a few would go along (the New Jersey supreme court certainly has set a precedent for itself with the replace of Torricelli with Lautenberg), it would be beyond the 'Rats reach to get enough states to go along to be able to win.
Moreover, the stink would kill them in any close state, especially if the name on the ballot was still "Kerry", but voters were supposed to vote for "Kerry" in order to get, say, Hitlary. Yeah, the corrupt and the radical leftists, but I repeat myself, would go along. But this would lose a majority of the "silent majority".
