Yep. I figure fraud is worth a couple of million votes to the Slave Party, but numbers like those cited above would easily overwhelm such an effort. They don't. Fruther, conservatives are usually more likely to show up at the polls.
Not in 2004....both bases were pretty equally mobilized. I work in Philadelphia and it was literally a zoo. I'm assuming a similar situation occurred in other Blue states as well. Not many lines but oddly enough, Philly voted at 100% of registered voters, with 80% going to Kerry. Except for Philly and one or two suburbs, and Allegheny County which encompasses Pittsburg, the rest of the state is pretty strongly Red. In those areas, there were lines in which people waited for hours (I guess the reason that there weren't lines in the city is that dead people don't have to wait.)
