Mayor Nutter seems to be taking very seriously the idea of his predecessor, former Mayor John Street, challenging his bid for a second term in the Nov. 8 general election.  Nutter's campaign just released a poll that shows him holding a comfortable lead over Street and Karen Brown, the GOP nominee.

Brown seems an after-thought in this poll, while Nutter's team seems fixed on Street, who has emerged as a fierce critic of the current administration.  Nutter's campaign stressed that he holds an edge among African-American voters over Street.  Previous polls have found that white voters in the city like Nutter better than African-American voters.

The poll memo from the Garin-Hart-Yang Research Group said Nutter has a 67 percent positive rating and a 16 percent negative rating.  It adds that Street "has an astounding 77 percent negative rating among white voters while Mayor Nutter is 20 percentage points MORE popular than former Mayor Street in the African-American community."

The poll memo does not included actual break-outs by race on how voters answered each of the questions.  PhillyClout has asked Nutter's campaign to provide them. We'll update if we get those numbers.

In a three-way race, the poll found that Nutter would win with 67 percent of the general election vote while Brown would get 14 percent and Street would get 13 percent.  In a Nutter-Brown match-up, he wins 74 to 17 percent.

The poll of 503 likely general election voters, conducted May 31 and June 1, has a margin of error of 4.5 percent.
