A bunch of reasons, I guess. Sometimes, because it cheers me up: Last night, Keith Olbermann had on a foreign-policy expert who said that Hillary may well bring with her to the State Department some advisers who are “neoconservative fellow travelers” with a history of supporting the Iraq War. The commenter did not seem to be as light-hearted about this news as I would be; and I sheepishly admit that that, for me, is a great part of the fun.
