American Crossroads on Tuesday launched a new television ad in Florida accusing Sen. Bill Nelson of slashing Medicare funding.

The new 30-second ad, which is supported by a $1.8 million buy, will run on local broadcast and cable stations in Florida for one week.

The ad repeats a claim made frequently by the Romney campaign that Obama cut $700 billion in Medicare benefits to pay for the health care overhaul.

The ad claims Nelson cast the deciding vote for ObamaCare. The U.S. Chamber of Commerce and the 60 Plus Association also ran spots casting Nelson as the deciding vote on healthcare– a charge which PolitiFact determined was false.

The spot also takes aim at a provision of the law that sets up a 15-person Independent Payment Advisory Board (IPAB) charged with making recommendations to slow the growth of Medicare costs, suggesting an “unelected board could decide to cut Medicare spending.”
