I would like to see a leftist elected for once and see if the corporatists can get him/her to move towards the center.
Get them into the party and pull the trigger. Chances are they will win.
If that is not the game then the thread needs to morph into a realistic discussion about how to make a third party candidate win the White House for the first time in history.
With the DNC, DCCC, DLC, DSCC, etc, working against left wing candidates it might be easier to run a third party. This wouldn't be ideal but it is the reality. The party has been run by corporations and Ivy League for so long that it views leftist politicians as a threat. At some point, more and more people are realizing they don't have a home in club democrat. I don't think were there yet. A few more cycles of self interested policies and waffling on populist promises perhaps. The demographics are favoring a left turn. I see no sign that the corporate smart set is willing to embrace this shift, preferring marginalizing that potential base instead.
