Wisconsin’s public workers are still deadlocked in a fierce battle with Gov. Scott Walker, but one blogger has his number—literally and figuratively. Ian Murphy, a writer for the Buffalo Beast, says he posed as businessman David Koch, a major funder of conservative and libertarian causes, and managed to get through to Walker, engaging him in—and recording—a somewhat embarrassing conversation. The ersatz Koch offers favors, draws Walker into an objectifying remark about MSNBC host Mika Brzezinski, and gets him to tip his hand on a procedural trick to draw Democratic senators back to the state after fleeing to Illinois. Walker’s office confirmed the recordings are genuine on Wednesday.
