MEXICO CITY (AP) — As Mexico prepares for its first-of-three presidential debates, the ruling party is struggling to remain relevant in the campaign ahead of the July 1 presidential election.

Advertisements for Institutional Revolutionary Party candidate Jose Antonio Meade have dropped the party's logo. Instead they use three colored triangles meant to represent the parties in his coalition.

That decision makes sense given the striking unpopularity of the ruling party, known as the PRI.

In a face-to-face poll of 1,200 voters published Wednesday by the newspaper Reforma, 59 percent said their most important goal in the elections was to get the PRI out of office.

An additional 22 percent said they wanted to prevent front-runner Andres Manuel Lopez Obrador from reaching the presidency. The poll had a margin of error of 3.7 percentage points.
