People who believe 2000 (and 1960 for that matter) were stolen are almost as stupid, and even more annoying, than 911 truthers.
It is nearly indisputable that neither Katherine Harris nor the U.S. Supreme Court had any interest in counting all the votes, instead just wanting to ensure that Bush won. Whether that counts as "stealing" is debatable, since it's not indisputable that Gore would have won had the recounts completed, but no one can deny that Gore would have won Florida handily had tens of thousands of blacks not been "mistakenly" stricken from the rolls OR had Palm Beach County not used a confusing ballot.
Even if you disagree with the above statements, you still must realize that nearly all Democrats agree with them. Comparing that to 9/11 trutherism, a fringe theory that virtually no one believes, is over the top.
