I'm really fortunate that I live in a district that was never really in question, so I didn't see nearly as many election ads as I could have.I just chalk it up to an ad revenue. YouTube needs cash (they've never been profitable as far as I have known), and whoever wants to pony up the dough they'll take it from anyone.
Honestly I'm just glad I don't have to see anymore VOTE FOR ME ads I was so sick of seeing them.
