Hyopthetically, even if Nader did do this, I don't think it would work the way the article writer suggests.
Lets suppose a state ends up with:
Bush 48%
Kerry 47%
Nader 3%
Other 2%
In this situation, I think Bush ends up being the winner, even if Kerry and Nader had the same slate of electors and their combined total ends up winning. Kerry and Nader were on the ballot seperately, so their votes must be tallied as seperate from each other.
I see a court case looming if Dems tried to say the Kerry slate of electors won, in this hypothetical.
If that happens adn somehow Kerry ends up winning, it would spell the end of the EC. And rightfully so.
