He's a REPUBLICAN governor who just won re-election. You think any cheating by him would not be uncovered and used by Dem operatives?
Democrats can bang young interns in the Oval Office and engage in forcible rape, and the media will refuse to cover it. A Republican can't make an off-color joke and not have it be 24/7 coverage for the following year (ask Clarence Thomas).
My guess is he’s good at being discreet with his sluts and his sluts were discreet too.
Republican politicians can be so good at being discreet Dem ops can’t catch them. Look at Thad Cochran for example
