There are more than enough reasons for the RNC to hammer Clark with enough ammo to make him look extremely weak.
Reason #1 - RNC folks will supply footages after footages of Clark praising * and his cronies. They can point out one of Clark's early mistakes by showing that he was an Independent after declaring his candidancy.
Reason #2 - Clark's maximum public funds is 45 million vs *'s 200 million warchest. How can Clark defend himself? Clark will be outspent on a 5 to 1 margin.
Reason #3 - All fluff and no real substance. Most of you like to argue that Clark has political experience because he's a General. That part is partially true. Yes, military is politics, but his dabbling is severly limited. Many will wonder about his truth on Kosovo campaign. What else can Clark offer that has true experience besides his military and foreign experience? Teaching cadets economics isn't experience. Applying economics are, and Clark has no experience whatsoever.
Reason #4 - His being on the board of most right-wing thinktank and defense boards questions Clark's truth on being "left". My opinion based on those is that if he's a Democrat, he's a DINO.
I am pretty sure that there are more reasons, but I won't get into them, since I want a debate. Convince me why Clark is your man. Why isn't Dean any different?
