UPDATE: Blunt has now signed the pledge.
Chuck Purgason put a little pressure on Roy Blunt yesterday by signing a Club for Growth pledge to seek the repeal of federal health care legislation expected to be approved this year by Congress, if he's elected to the US Senate. Blunt, in response, said he'll vote against the compromise health care bill (shocking!) -- but stopped short of signing the Club for Growth pledge.
Blunt has long been at odds with the CFG, which has a history of slash-and-burn tactics in support of it's very conservative platform on taxes and spending. They've been especially critical of his support for earmarks, and have consistently given him low marks in their annual "RePORK Cards" they say "measure the dedication of their representatives to changing the culture of corruption that surrounds pork-barrel spending."
