A general comment on American politics and the situation in Iowa and New Hampshire:
As the war drags on and the economy slides, it will get easier -it already has- for the rest of the Democratic contenders to speak out. The more timid candidates will have 'permission' to be impolite. This may not be good for the two who spoke first, who may become sacrificial lambs on the altar of consensus, but it's good for the Dems as a whole.

It's interesting that Dean now is getting a long list of name supporters as he's beginning to slide into the pack.
