@fbaezer,
It seems that Mikel Arriola has read the polls too, and he moved to the right, defending "traditional family values", against the legalization of pot and gay couples adopting.
He tries to pick some of the conservative PAN voters, unconfortable with having a left wing candidate for the city, due to their party's alliance. That would never be anough to win, but could prevent him from going one digit.
But doing this, he may allienate some of the lay State supporters of PRI.
