A new Economista/Mitofsky poll for the Mexico State gubernatorial race shows Morena candidate Delfina Gómez with a slim lead over the PRI-ista Alfredo Del Mazo. The campaigns end this coming Wednesday, and the vote is on Sunday, June 4.
The poll was carried out from May 25-27, and gives Gómez a 3.5% lead over Del Mazo. According to Mitofsky, Del Mazo peaked at the beginning of May and has been losing ground, with the Morena candidate being the main beneficiary. The other two main candidates, Josefina Vázquez of the PAN and Juan Zepeda of the PRD have held steady The 1,000 person poll has a statistical margin of error of ±3.1%.
The poll probably does not reflect the May 26 announcement by the PT candidate Óscar González, who is polling at 2%, withdrawing and asking his supporters to back Gómez.
Other recent polls have shown Del Mazo with a lead, and most observers think the determining factor will be voter turnout, which has historically been 50% or less for gubernatorial elections in the state.
