Both picked useless running mates too.
you think Lieberman was useless? Florida's Jewish population is sometimes overestimated but with margins this close it makes a difference. Plus he carried himself well in the campaign. He didn't make any major gaffes, or come under any comments questioning his seriousness or ability like Quayle or Edwards did.
True...but he did hurt Gore among the Muslims, who were at the time actually Republican-leaning. He was an overall good for Gore's electoral prospects nonwithstanding - the Jewish vote outnumbered the Muslim vote in 2000. I also think he helped Gore among moderates, though this was blunted because of the momentum that Bush had going into Election Day.
