Whoever had the brilliant idea of making Capricia Marshall a guest on MSNBC's "1600 Pennsylvania Avenue" last night was probably hiding from host David Gregory when the show ended.  Marshall turned out to be the least forthcoming guest I have ever seen on a political talk show.  The aide to Hillary Clinton put up a smiling stonewall that would make G. Gordon Liddy—who chose a stiff prison sentence over Watergate stool-pigeonhood—proud.

Marshall is the director of Hillary Clinton's political action committee, Hillpac, and former social secretary in the Clinton White House.  Gregory had her on in the clear expectation that she would dish on Hillary's prospective appointment as Secretary of State.  But Capricia was tighter than the proverbial clam.  Try as Gregory might, Marshall wouldn't give up the smallest shadow of a hint of a scrap of a tidbit about anything of interest.  Her big revelation? She's excited about the inauguration.  Gag Gregory with an NBC "Yes We Can!" commemorative Obama-campaign DVD.
