Bersin is a big democrat activist who worked for various leftwing causes before being made US Attorney under the Clinton Administration. Clinton then appointed him to be the "border czar," reporting directly to Janet Reno. He was a long-time attorney for Munger Tolles (a firm closely associated with Warren Buffett).

He'll know where all the rotten apples are in the public school barrel.
He's going after the unions and has Gov. Arnold's blessing, so he can't be "all bad."
