Aside from reform, the DNC faces an image problem with the whole "liberal" paradigm promoted by Faux News and Libaugh. I see Dean as an opportunity to counter that image. Frost and Roemer play into their paradigm that the Democratic party is too liberal. We need somebody to point out that Bush and Sessions and Inhofe are total wackjobs. Not politely and circimspectly, but loudly and obnoxiously.
I would hope that Dean would be smart enough to utilize Frost if he was willing to go on the stump and be the right wing attack dog the Democratic party needs. My concern is that Frost would be restrained from making that case as DNC Chair. We need a vicious attack dog who can tear into the radical conservatives and that person probably can't be DNC Chair.
By the way, I just saw Sen. Dayton on The Daily Show and it was as good as I could have expected. "I don't like being lied to, repeatedly." is as close to straight out calling Rice a liar as I could hope for. I hope Dayton and Boxer are setting the tone for the next session of Congress.
I'm rambling and off topic, but its late. I'll quit now.
I just posted something on dKos about Frost as a MODERATE voice with a LIBERAL agenda--I think this is where his appeal lies. He is able to speak to the widest audience of all the candidates while still maintaining his core Democratic principles.
