In a nutshell: While Elba Esther Gordillo certainly made a pact with Calderón in 2006, in an unseemly votes-for-political positions, the value of her votes are vastly exaggerated.
Why? While it is well known that her party PANAL received far more votes for its list of national deputies than for its presidential candidate - herein was the very bargain, where the SNTE-organized teachers and their families would vote for Calderón for president and their own party for lawmakers - yet a a forthcoming study by Javier Aparacio, one of CIDE's very sharpest minds, now reveals that of the SNTE/PANAL teachers, only 22 percent actually followed the order to so, while 27 percent voted for AMLO.
What does this mean? That Calderón paid a very heavy price for very little, and that Gordillo's bargaining power with regards to her PANAL party may be a castle made of sand: She does not deliver.
Party leaders, take note.
