When somebody pulls out this old gripe, they reveal themselves, unequivocally, to be a moron.
If the Electoral College did not exist, there is no reason to assume that the popular vote in 2000 would have even remotely resembled the voting that actually occurred. Each candidate would have campaigned differently, and the party apparatus would have worked to get the vote out in all districts, whether the state were firmly in one camp or not.
There is no way to know what the the nationwide popular vote would have been like, but you can be pretty certain that it would not have been anything like the narrow margin between Algore and President Bush.
Slathering on the lie that the election was decided in the Supreme Court is just icing on the cake.
It's like claiming your team would have one the Superbowl if they played it with a baseball instead of a football.
