Or watch archives of Bill C - the pervert
Clinton is a poor example of plausible deniability. He's a policy wonk, intelligent, and legendary for lying. The baseline assumption would be that he probably knows, and if not, he should have known.
I'd rather be known as someone who beat a retard getting into office than someone who screwed one and lied while already there.
Bush is an excellent example of plausible deniability. He's not into details (granted he doesn't have any big ideas either), not particularly intelligent or intellectual curious, and . . . he's simple. The baseline assumption is that he doesn't know and even if you told him he won't understand.
GHWB ran the CIA. He knows. He knows everybody else that knows.
Reagan was significantly more intelligent than W, maybe. He was not into details but he did have a few ideas. So he could deny WHAT or HOW something happened but he probably knew WHY (purpose). For those of you unaware about Alzheimer disease . . . Reagan's dementia was significant during his presidency. At baseline he might know but often forgot. And if he wasn't suppose to know he would forget with greater efficacy.
