Hey, kossers, check out this organization:
Operation Truth.
Started by a bunch of Iraq vets, this group has been endorsed by Ventura, Muller and several other prominent veterans. It is nominally nonpartisan, but their basic message is that "the government isn't telling the full truth about the war." These guys are angry and demanding their message be heard, and they know what they're talking about.
You might have heard their ads lately on Air America - the ones with the machine gun audio. They are reportedly going to start airing some aggressive TV ads tomorrow. Keep watching their site.
I've met the founder, Lt Paul Rieckhoff. A remarkable guy. In the Reserves, he's served at Ground Zero in NYC, in the Iraq invasion, and in the occupation.
