The ad, which aired this June, is aimed at New Hampshire rep. Charlie Bass who voted for the Ryan plan — and who endorsed Mitt Romney. Democrats know this is a winning issue for them. Republicans were scared by this very ad this summer and tried to get it taken off the air. But, as progressives want to remind them, they, and whoever their nominee is, have already yoked themselves to the Ryan plan. PCCC spokesman Neil Sroka gave the following statement on the ad buy: Tea Party Representative Charlie Bass voted to end Medicare and this issue is one of the reasons he endorsed Mitt Romney. By airing this ad during this weekend’s New Hampshire presidential debates, we are holding Charlie Bass accountable for voting to end Medicare and making sure that Republican presidential candidates cannot escape their party’s extremism on this issue.

That's the ad progressive groups Progressive Change Campaign Committee and Democracy for America are running in New Hampshire this weekend, to coincide with the GOP presidential debate and upcoming primary in that state.

Romney has whole-heartedly embraced the Ryan plan to end Medicare. That wasn't quite enough for Rick Santorum, who wants to destroy all vestiges of the program.

The ad will provide a nice reminder to New Hampshire voters of just how radical their Republican choices are. It's also a harbinger of the narrative Democrats and liberal groups will be hammering for the next 11 months. House Republicans voted nearly unanimously to end Medicare, and whoever ends up being the Republican nominee for president has endorsed that vote.
