Do you have a link or other evidence to support your claim that there were districts in PA with 100% turnout, with 100% of votes going to the Democrat candidate? (I'm assuming he/she is not running unopposed)
I would be very interested in seeing this. With supporting evidence, this story could be more widely spread for sure.
I will do some searching. I just remember reading something in the newspaper immediately after the 2000 election claiming a 100 percent turnout at some Philly voting precincts, with all or nearly all the votes going for Gore.
Also by experience, I can attest to many unusual practices in some local precincts in Philly, where the voting booths on some blocks are set up in a basement of various local establishments.
