Battman called DiCara's chances "very realistic." citing increased money contribution following the Kiley endorsement Wednesday.

Kearney, who has been buying TV time for a month, will conduct an extensive phone campaign, to be followed by mailings, spokesman Gregg Wilson said yesterday. Wilson added that the campaign, which is considered by many to be the best organized in the field, will try to bring many as 35,000voters on election day.

An informed source wins is not involved in the race said yesterday that Kearney campaign organization is better than that of Mayor White "at his height,? The source who asked not to be identified, added that Kearney was the only local politics who was able to provide campaign workers last year for the election bids of Governor Michael S.
