As to "voter turnout over 100%" please name one place, with citation. This meme started with Jude Wanniski in 2000, claiming it for Philadelphia. I have carefully checked official data there, and elsewhere, and have challenged every time it appears, and never gotten a cite. It just isn't so -- Philly ran about 60% turnout of registered. Registrations were too high (lack of purging), but turnout still wasn't improbably high as percentage of voting-age citizen population. 99% for Gore or Kerry in some precincts, yes. 99 (or even 90) + % of registered voting, no.
And note, that dems make exactly the same claim for rural Ohio in 2004 -- with equally absent data -- except for one place where all the supplementary paper ballots for 6 precincts were mistakenly reported as being from a single one of those precincts.
