Al Gore
The 2000 election was stolen from him partly due to the actions of Dubya's brother, who was governor of Florida at the time. Jeb stopped the count right when ballots that were from counties favorable to Gore started to come. And this is not even getting into the Supreme Court's role in handling the presidency to Dubya.
It has nothing to do "voter apathy" or anything related to Gore really (outside of him capitulating and taken the blatant theft like a complete chump). The 2000 election was a fraud election. "Uh aktually we have to vote enough that the GOP can't have room to steal the election" is loser shit, which is why blue MAGA has to pretend the 2000 election was legitimate like the pathetic losers they are. At least red MAGA has it in them to say that the 2020 election was stolen while blue MAGA can't even question the legitimacy of the 2000 election results.
