If Karl Rove can screw around in a Democratic Primary with memos to Team Obama in the WSJ, why can't Bill Clinton screw around in a Republican Primary with comments to the NYT?
Bill Clinton is many things to many people, but one thing he is to everybody is a brilliant political strategist (even if you think his tactics are despicable).
And Bill Clinton is absolutely terrified that Johnny Mac is going to be successful in the Republican Primary.
Which is why John and Hillary are such good friends. According to Bill Clinton.
