There is NOTHING that could be released on either of the Clintons that will make them less likely to return to the WH. No matter what it is, the MSM will blame those horrible conservatives cringing in the high grass for floating ugly rumors, and it will stick to the Republicans like glue while the Clintons become victims and martyrs.
And just for a nice finishing touch, the MSM will then smear one of the Republican candidates to make certain no one misses how hypocrital all of them are.
Bingo, that is why they are keeping Larry Craig around, for a few more minutes of Republican hypocrisy.
