MOUNT VERNON - While Westchester County Executive Rob Astorino might be gaining some traction in the polls, the Rev. Al Sharpton came out swinging against him this weekend warning voters that Astorino isn't ready for the state's top job of governor.

The outspoken pastor and civil rights activist spoke at Grace Baptist Church. "You all tell the county leader that usually to get a promotion, you do the job you already have," said Sharpton.

In an interview with News 12, Rev. Sharpton went on to say that the county executive isn't ready and attacked Astorino's inability to make affordable housing work in Westchester. "What I'm questioning is the quality of leadership,” he said.

Sharpton wasn't just sounding off on politics. He is also outspoken about issues of racism in Westchester. He says he was frustrated to learn about racist tweets from Mahopac High School students toward the Mount Vernon boys' basketball team after a loss on the court. 

Astorino is expected to officially receive the Republican nomination at the GOP convention in Westchester this May. According to a new Sienna poll out Monday, Cuomo is still far ahead with 61 percent of the vote compared to Astorino's 26 percent.
