"If you can't get the swing voters to vote for the existing level of conservatism the GOP is offering, it seems odd to argue that the GOP needs to peddle an even more strident form of conservatism."
Come on, Jonah. Romney did just find with so-called "swing voters"-- he beat Obama among independents. He lost because many conservatives stayed home (foolishly, in my opinion) because they refused to vote for "Obama-lite," which turned out to be a de facto vote for the Idiot-in-Chief.
You can't possibly believe that Romney lost because he was too stridently conservative.
