Seems the Oregon Democrat is mighty upset about that new paper from the Justice Department and wants more information about the legal justification for drone strikes against U.S. citizens suspected of terrorism, and he promised to “pull out all the stops” to get what he’s looking for, Roll Call reports.

And for days, there’s been will-they-or-won’t-they speculation that Republicans could potentially, perhaps, filibuster the nomination of one of their own, former Sen. Chuck Hagel (R-Neb.) to be secretary of defense.

Which puts us in the topsy-turvy position of having a Democrat threaten a Democratic nominee with filibuster, while Republicans warn they could do the same to a Republican.

Nevermind that it’s all posturing — filibusters of Cabinet nominees on either side are unlikely, or at least they’re unprecedented.

Which is good to remember before you pop something to relieve the vertigo.
