I think Hillary wants it that way. It makes her look moderate and thoughtful to have the papier mache heads, drum and dreadlocks crowd booing her.
What you say is true when they are nailing her on ideological grounds.
But my point is that they are nailing her on the character issue.
I find that very interesting.
I do agree with your premise, however.
Howard Dean not only makes the clintons look moderate.
He makes them look sane. (To the casual observer, anyway.)
