This line-of-attack has 2 goals:
(1) Get rid of Dean (as a non-Vet of any type, he can't even participate in this debate), and
(2) neutralize the 'Vietnam-issue' (which can really hurt Sen. Kerry).
It's a high-risk strategy on the part of the Democrats. And Terry McAwful is the holder of the rug upon which Sen. Kerry stands -- meaning the Clintons can do him in at any time.
And with all this other crap about Fonda, US troops under UN control, his own past will ruin his chance.
