With respect to this article, while I strongly feel Democrats are getting an unfair shake from PolitiFact, and while I think it’s self-evident that Republicans voted to end Medicare (over time, in phases, but end it nonetheless), there are other, erm, quality control issues with the DCCC ad in question
More specifically, the ad is terrible.
It’s hard to muddle a message as simple as “Republicans Voted To End Medicare,” but by turning it into a punchline for ironic 20-somethings, they did exactly that. Judge for yourself.
