Sullivan is an idiot, but he is right that there is a certain section of the base that cares about federalism only when it suits their ends and not otherwise.
That said, he exaggerates that section's size and distorts the extent of their positions and oversimplifies the Gay Marriage issue far too much.
Sullivan is a single issue voter, though the issue changes by the minute. Sodomite marriage seems to be all he cares about at the moment but the next CNN story can change it back to the issue he loves to beat Bush up with and that is the alleged torture of Islamo Fascists.
I gave up on Sullivan when he said he wanted to fight the war against the Islamists but was voting for John Kerry.
