From E.J. Dionne at Post Partisan at The Washington Post:
I don’t think Rep. Michele Bachmann, the very right-wing Republican from Minnesota, is doing her party any favors by creating a Tea Party Caucus in the House of Representatives. In fact, I imagine that this is the first thing Bachmann has done in a long time that will make Democrats happy.
Not surprisingly, Bachmann declared herself chair of the caucus, for which she filed paperwork on Thursday.
