Senator Rand Paul's (R-KY) old-school talk-until-you-drop filibuster yesterday got people talking about drones again. The senator, aided by his tea party colleagues including Ted Cruz and Marco Rubio, insisted that the administration address whether drones could be used to kill Americans on American soil.
