EdoMex Alliance: Not Dead Yet

Gustavo Madero said that even with the candidacy of Alejandro Encinas, the PAN is not ruling out an alliance in Mexico State, saying it is watching the situation "with reserve, but with interest". This seems like it would be a hard sell among party faithful, given that Encinas is close to AMLO (although Madero tried to soft-pedal that by referring to his "changes of definition in his political participation). If they do make it happen, you wonder what would be the limit for alliance supporters in trying to prevent Peña Nieto from winning the presidency. I ask only slightly in jest: Would the panista alliance supporters support an AMLO candidacy if only to make it harder for Peña Nieto to win?
