In a conference call just now, the Clinton campaign called on Barack Obama to fire Samantha Power for calling Hillary a "monster."

There are advisers and then there are advisers. Power is Barack Obama's Condi Rice.

A Harvard Law grad, former foreign correspondent, and Pulitzer Prize winning author, Power left her Harvard faculty gig to go work on Obama's Senate staff for a year. It might be a little condescending to say she schooled him on foreign policy, but that's close to accurate. In the constellation of Obama advisers, the 37-year-old Irish-born Power has as high a profile and as close a relationship to the candidate as anyone.

All of which is to say that her intemperate comments have put her and Obama in a bind -- and the Clinton campaign knows it.
