SAN JOSE (Reuters) - A former president of Costa Rica leads the Central American country's presidential race, but he has only modest support and many voters are undecided about which candidate to choose, an opinion poll for the Feb. 6 contest showed on Wednesday.

Among the 63% of respondents planning to vote, 48% have not yet picked a candidate to replace President Carlos Alvarado, the Oct. 21-Nov. 2 survey of 940 voters by the University of Costa Rica's Center for Research and Political Studies (CIEP) showed.
