Further Evidence That a Presidential Alliance is Unlikely

Ebrard told El Universal he doesn't see a PRD-PAN alliance in 2012. You'd think that barring a radical change in the power structure of the PRD, Ebrard and everyone to the left of him being against an alliance would make it unfeasible. Although it would be interesting to see what would happen if AMLO runs and Ebrard doesn't; would Ortega and other anti-AMLO perredistas support a moderate panista in such a scenario? Would they run one of their own? Or would they bite the bullet and tepidly support AMLO?
