To be honest, I was surprised when Dean didn't say "This isn't as bad as Watergate," because, after all, HE was involved with that and it's his claim to fame, and he and Woodward and Bernstein without fail come out and say that, no matter what the situation.
The entire time, I just think that they both felt like they have finally hit upon the 'fatal bullet' that will once and for all rid them of those pesky conservatives: "They're certifiable."
Their strategy to win in 2006 and 2008 is to say we're scary and crazy.
Woodward should just tattoo "This isn't as bad as Watergate" on his forehead to save the strain on his vocal chords.
