Support for the frontrunner in Mexico’s presidential race, opposition candidate Enrique Pena Nieto, fell by 2.6 percentage points in the first poll of the year after a series of public gaffes dented his lead.

The poll, conducted by Consulta Mitofsky, showed the former governor from the populous State of Mexico garnering 42 percent support when compared to the other two top candidates, a dip from the last survey in November when he received 44.6 percent.
