Argentine president poised for re-election: polls

Fernandez's support now stands at 53.2 percent, according to the latest monthly survey by local pollsters Management & Fit showed. That puts her more than 40 points ahead of her nearest rival, Socialist provincial governor Hermes Binner.

A Poliarquia poll for leading daily La Nacion gave support of 49.3 percent but a projected vote of between 52 percent and 55 percent considering voters who are still undecided.

Center-leftist Fernandez won just over 50 percent of votes in an August primary, which was seen as a dress rehearsal for the October 23 election because all parties had already anointed their candidates and voters could choose among them.

Binner has voter support of 12.4 percent, up from 11.6 percent last month and consolidating his position as Fernandez's nearest rival, Management & Fit's survey showed.

The Poliarquia poll also put Binner in second place with support of 13.6 percent and a projected vote of between 14 percent and 16 percent.

Trailing in third in both polls was Ricardo Alfonsin, a social democratic legislator, who had support of 7.8 percent and 9.5 percent in the polls.
