I mostly see ads for candidates I couldn't possibly vote for, unless ACORN forces me to commit voter fraud. Yes Philly is a big media market, but I know Comcast allows for hyperlocal advertising to cable customers. I assume they don't control infinite slots on infinite channels, but they do at least control some slots on some sports channels, those shows that people actually still watch live and don't just fast forward through.
I keep asking this question and never quite get a satisfactory answer. Why do I see so many ads for people in Jersey and the burbs? Maybe ad buyers know what they're doing. I don't know.
