He worked for his country. Ambassador to China is a sensitive and vital position. With Huntsman’s extensive knowledge of the Far East, Obama probably thought he was being clever. Give a potential rival the post, clear him out of the way as a 2012 obstacle to re-election, AND look bi-partisan in the process. Hasn’t quite worked out that way though!
He was also Ambassador to Singapore under President George H.W. Bush, of course.
No, he served the usurper. He is a sniveling little quisling. He deserves a quick and speedy trial for treason, followed by some stout rope.
