(CNN) - Eliot Spitzer's main rival in the New York City comptroller race will not challenge his petition signatures.
A spokesperson for Scott Stringer confirmed Friday that the Manhattan borough president will not attempt to drag out the qualifying process for the Democratic primary ballot.
Spitzer announced late Thursday, shortly before the midnight deadline, that he had obtained 27,000 signatures since he first started collecting names on Monday. He needs 3,750 valid signatures to get on the ballot.
Responding to Stringer's decision, Spitzer's spokesperson said the former New York governor is "thankful" to those who lent their support.
"He looks forward to making the case every day for an independent comptroller for the City of New York," the spokesperson said in a statement.
Before Spitzer announced his late entry into the race on Sunday, Stringer was widely considered the frontrunner in the race.
A new poll released Wednesday, however, indicated Spitzer has the edge over Stringer. The former governor has 42% support among registered Democrats, compared to Stringer at 33%, according to the NBC 4/Wall Street Journal/Marist poll.
Spitzer resigned his role as governor in 2008 after getting caught in a prostitution scandal.
