The Republicans are casting about for a candidate for President in 2016, and Chris Christie of New Jersey and Scott Walker of Wisconsin have been prominently mentioned for a while.

But both of them have gathering scandal clouds overhead. In Walker’s case it’s possible collusion with outside campaign groups to coordinate political activity, one of the few campaign laws the Supreme Court hasn’t yet determined is unconstitutional. In Christie’s case it’s the famous closing of the George Washington Bridge and the diversion of Port Authority funds to fund New Jersey projects.

The bench is looking a little weak.
