Democratic Hydra: Which Head Speaks Today?

Which head of the five-headed Democratic Party speaks for its constituents today? Five separate philosophies are running for the Presidency in '08 and each claim that it speaks for the party.
It time now to give a little therapy to each one of these heads and try to see (finally) which philosophy voters should consider before pulling that Republican-rigged lever.
Black and white differences envelop that party to such an extent that sheer hatred of the president seems to be the glue holding it together. Thus hatred and not a "unity of philosophy" is the single motivating factor in this upcoming election.
Consider:
First we have the doves, the anti-war crowd. They want peace. Spokesmen like Cindy Sheehan travel the world demanding a stop to all the fighting. John Edwards is their poster candidate followed by Obama.If this were 1968, this would be called the Peace Movement...and paisley would be the party color. Thus one head of the hydra consists of the "peace and love" set.
Second, we have the "cut and runners". This group feels that we have already lost, that we should retreat "over the horizon" to as far away as Okinawa if necessary and that our troops there are "under pressure" and also that a draft is necessary to continue operations. This is the "Murtha head" of the hydra.Pelosi and Reid are also charter members.
Third, we have the group that wants to partition Iraq into three parts: The Joe Biden group. This one even has one Republican hopeful saying the same thing now.
Fifth,we have the "no game planners". This group castigates the president on every single decision that is made in Iraq, and Monday morning quarterbacks everything, yet has failed until this very moment to put fourth an alternative plan. This is the Clinton head of the hydra.
Thus the five-headed hydra comprises the opposition...five diametrically opposed view points simultaneously claiming that they speak for their party.
So, before we pull the lever in November 2008,, I'd like to ask: Which one of these hydra-heads actually speaks for the Democratic Party?
Does anyone know? Should not the American people know before they pull that Republican-rigged lever?
