Calderón's popularity in Mexico currently sits at 66%, up from 57% in November and this is the highest it's been during his Presidency so far.

In another poll, 63% of PRD (AMLO's party) members say the next party leader should recognize Calderón as the legitimate president (which AMLO refuses to do) and 77% say the PRD should cooperate with Calderón in the legislature (which AMLO refuses to do). Here is an article in English about the trials of the Mexican Left.
