Crossroads GPS, the Karl Rove-helmed “super PAC,” is airing a new ad in the 19th Congressional District race between Rep. Chris Gibson and Democratic challenger Julian Schreibman.

In the spot, it’s noted that Schreibman supports — but couldn’t have voted for — the 2010 health care law that diverted $716 billion in Medicare subsidies over 10 years to fund it in part.

The ad was first reported by Politico and quickly denounced by the Schreibman campaign.

“Rove’s TV ad in support of Congressman Gibson is the same old political attack we’ve seen coming from the Washington DC Tea Partiers for years. It attacks Julian for a cut to Medicare that Congressman Gibson actually voted for when he supported Paul Ryan’s budget in 2011- a budget he referred to as ‘my plan.’”

While the Crossroads effort is a seriously well-funded political action committee, the Schreibman campaign can take some solace that he’s caught the attention of Rove, a villain to liberal and Democratic voters.

Crossroads is also airing in the NY-1, where Republicans feel they can unseat Rep. Tim Bishop with Randy Altschuler.
