DS at Diplopundit — who I gather is a Foreign Service Officer…? – points out that there’s a cloture vote for Chris Hill’s nomination to be ambassador to Iraq on the Senate calendar for April 20 at 5:30 p.m., the first day back from the Congressional recess. I left a message with a spokeswoman for Sen. Sam Brownback (R-Kan.), Hill’s principal critic, trying to get Brownback’s reaction. But unless Brownback can suddenly rally 40 other senators to oppose Hill — despite the support of Sen. Richard Lugar (R-Ind.), Gens. David Petraeus and Ray Odierno, and Defense Secretary Bob Gates, to name a few — Hill’s on his way to Baghdad.
