Matthew Yglesias highlights how crazy the right (those in the press and otherwise) are going over Nancy Pelosi going to Syria.
Me, I say let 'em stew. The American public that could conceivably vote for Pelosi's party aren't going to be swayed by this, not anymore. Lines about how "America needs to speak with one voice" have always been nonsense, as Matt correctly points out. The president sets official policy, but unofficial positions and debates are as old as diplomacy, and the niceties of official policymaking aren't of interest to anybody outside Foggy Bottom and editorial writers with no memory beyond the last news cycle.
These guys are just ticked that the president can't dictate to the Speaker anymore.
