President Obama on Monday endorsed Democrat Bill de Blasio for mayor of New York City.

“Progressive change is the centerpiece of Bill de Blasio's vision for New York City, and it's why he will be a great mayor of America's largest city,” Obama said in a statement.

Obama praised de Blasio’s policy agenda, saying it is “marked by bold, courageous ideas that address the great challenges of our time.”

De Blasio, whom polls show is the clear front-runner against Republican Joe Lhota, said he was “deeply honored by President Obama’s endorsement,” in a statement.

“If I am fortunate to earn the trust of the people of New York on November 5th, I will work every day to advance our shared value of making sure everyone has a fair shot,” he continued.

“On health care, tax fairness or the economy, the President is no stranger to addressing big problems with big ideas and big solutions. I will emulate the example he has set, and if elected I stand eager to work with him on an urban agenda that grows prosperity for all,” said de Blasio.

Obama's endorsement comes after former President Bill Clinton and his wife, former Secretary of State Hillary Clinton, also threw their support behind de Blasio last week.

The New York City public advocate won a tough Democratic primary, topping New York City Council Speaker Christine Quinn, former NYC Comptroller Bill Thompson and former U.S. Rep. Anthony Weiner, among others.
