SACRAMENTO — When a federal judge last year gave J. Clark Kelso sweeping powers to rehabilitate California’s ailing prison medical system, lawmakers generally hailed the law professor as an apolitical “Mr. Fix-it” with a resume of righting state programs run amok.

But on Wednesday Gov. Arnold Schwarzenegger and Attorney General Jerry Brown asked U.S. District Senior Judge Thelton Henderson to can Kelso, arguing that the prisons receiver plans to run hog wild with the state credit card in a secretive effort to transform prison hospitals into Club Meds for convicts.
