Oh come on. Some of the stuff in this thread is ridiculous. I get he's the beloved mascot around here, but he isn't gonna have the ASB magic wand necessary to make Bush the Lesser wise, help McCain beat Obama, or stop the GOP from drifting deeper into its Fox/Drudge/Rush echo chamber of madness. You're all putting too much stock in that "last liberal president" trope and acting like this guy didn't help invent or nurture many of the modern GOP's worst tendencies.
Woodward said in "State of Denial" that Kissinger was advising Bush that "victory is the only meaningful exit strategy" during the darkest days of Iraq and essentially treated it like a replay of the Vietnam War.
"This is so fascinating. Kissinger's fighting the Vietnam War again because, in his view, the problem in Vietnam was we lost our will."

I can see Dick giving similar "advice".
Its much more likely that Nixon encourages and cheerleads the last 20 years of Republican bullshit instead of standing athwart yelling stop imho. Shut down the impeachment? He'd probably be on Meet the Press insisting Clinton's scandals were worse than Watergate.
