E.J. Dionne: “Contrast Cameron’s deliberate effort to reach out to voters who, as he has put it, have “idealism and progressive ideals hard-wired into their DNA” with what’s happening in the Republican Party.  In today’s GOP, someone like Cameron would be condemned as a big-government sellout and buried under a mountain of tea bags…When as solid a conservative as Utah’s Sen. Bob Bennett is in danger of being denied renomination, you know that the right-wing Jacobins are on the march.”
