The Club For Growth has a website called "Repeal It" that lists candidates who have pledged to "sponsor and support legislation to repeal any federal health care takeover passed in 2010, and replace it with real reforms that lower health care costs without growing government."
Former Club president Pat Toomey has of course signed, and so have the following House candidates (all of them Republicans): Mary Beth Buchanan and Keith Rothfus in District 4; Paul Huber in 3; David Madeira in 10; and Frank Ryan in 17. (Can't remember which district is which? See our map!)
West Virginia business executive David McKinley -- who is looking to unseat US Rep. Alan Mollohan of Wheeling -- has also signed.
