If there ever was one. Still, nice piece on Grassley by Karen Tumulty. I think this quote from Jon Kyl tells the story:
Yet Grassley is not immune to the pressures from his party. Iowa Republicans have been trending rightward; socially conservative Arkansas governor Mike Huckabee won last year's presidential caucuses there. Opposition groups have been running ads in the state criticizing Grassley for his role in the health-care negotiations, and back in Washington, Senate GOP leaders have made no secret of their anxiety about it. "Senator Grassley has been given no authority to negotiate anything by all of us Republicans on that committee," said Jon Kyl of Arizona, the Senate GOP whip. What's more, Grassley's term as ranking Republican on the powerful tax-writing panel will expire at the end of 2010; he stands to assume that spot on the Judiciary Committee, but the Republican leadership could block him from getting it.
