A new poll in Mexico says the second- and third-place candidates in the presidential race are running neck and neck — but remain far behind the candidate of the country's former ruling party.

The poll released by the consulting firm Mitofsky says Enrique Pena Nieto of the Institutional Revolutionary Party is supported by 38 percent of those surveyed a little more than five weeks ahead of the July 1 election.

Andres Manuel Lopez Obrador of the leftist Democratic Revolution Party gets backing from 20.5 percent and Josefina Vazquez Mota of the now governing conservative National Action Party is supported by 20 percent.

The poll of 1,000 adults was conducted between May 18 and 20 and has a margin of error of three percentage points.
