Populist Reform of the Democratic Party

We have in some ways decreased our involvement in actual combat in the mid East and I recognize Obamas efforts to avoid war with Iran and his reluctance to invade other countries but we have expanded a military role into so many other countries and I just don't see it as s big campaign issue. Most Americans don't seem to care.
I voted for Hillary in 08 and just had to ignore her iraq war vote. I'm being frank. I ignored Kerry's vote in 04.
I looked at chafees voting record and he seems to be a free trade guy. He did vote to support some dem issues but I don't see him in the same populist light as Bernie who has been consistent in his votes.
To me opposing Iraq is not the only populist issue. Look at Webb he opposed Iraq but I wouldn't call him a progressive or populist. Warrens recent fight for the middle class and consumers is populist. Both she and Bernie have the advantage since they are both in the middle of the fight and people like chafee only have their voting record in the past to go on. He would have to make a compelling argument for me to call him a populist.
