Apparently you have not watched the Dem debates. Not a SINGLE democrat has pledged to completely withdraw troops from Iraq. The dirty little secret is the Dems are all for withdrawal while Bush is president so they can strap defeat around Bush's neck, but it will be whole different ball game when a Democrat is president. Playing to the Democrat lunatic fringe base and making actual policy decisions from the Oval Orifice are two different things.
Well except Kucinich.. but he is not an earthling.
