Philly mayor endorses Clinton

Philadelphia Mayor John Street endorsed Sen. Hillary Rodham Clinton (D-N.Y.) for president, the campaign announced Monday, giving the Democratic front-runner a boost after this weekend’s announcement that Sen.

“Senator Clinton is a progressive leader who has served the people of our country with dedication and passion for over 30 years,” said Street, a Democrat. “She will be a strong advocate for our nation’s cities.”

The endorsement adds to Clinton’s cachet as she continues to lead in the national polls.

Clinton raised $27 million.

Street joins Mayor Antonio Villaraigosa of Los Angeles in supporting Clinton, giving her mayoral endorsements from two of the six largest American cities.

Chicago’s Democratic mayor, Richard Daley, has endorsed Obama, and New York City’s mayor, Michael Bloomberg, is rumored to be contemplating his own independent run.

It is still unclear how Obama’s feat will affect Clinton. Her campaign pre-empted the second-quarter results by announcing last Thursday that Obama would out-raise Clinton.

Terry McAuliffe, Clinton’s campaign chairman, told CBS Monday that the team is looking forward to another boost this week when the former first lady campaigns in Iowa with her husband, who is expected to drum up further support.

 “I think what’s clear is that both candidates will have all the money that they need in order to run an effective race,” McAuliffe said. “But ultimately it comes down to who’s got the best message, who’s the best candidate.”
