"I actually, myself, believe that this idea of surging troops, escalating the war -- what Senator McCain has been talking about -- what I would call now the McCain doctrine ... (is) dead wrong," said Edwards.
Some of the criticism that progressives have had with an Edwards candidacy is that he is "too soft." This direct challenge to McCain should help quell some of those concerns. That it is also couched in terms of ending the war in Iraq should also further his credibility with progressives.
This tactic should also show that Edwards is in this to win it. I'll be looking forward to how this will play out. So far, there's no comment from McCain.
