Elections by Mexico's former ruling party too close to call

MEXICO CITY (AP) -- The two candidates to be the next president of Mexico's former ruling party put any thought of victory party on ice after initial results showed the election too close to call.

An official exit poll showed candidate Beatriz Paredes winning between 48.4 percent and 52.2 percent of the vote and Roberto Madrazo capturing anywhere from 47.8 percent to 51.6 percent, said Sen. Humberto Roque Villanueva, the official overseeing Sunday's Institutional Revolutionary Party election.

Roque said more official data would not be available until Monday.

A survey conducted for a private television station showed Paredes with 51.5 percent of the vote and Madrazo 49.6 percent.

Roque said more than 3 million people voted in the PRI's first-ever open internal election.
