Remember this the next time Obama and his surrogates argue for civility in politics.

PHILADELPHIA — When Mitt Romney came to an inner-city charter school here Thursday to promote his new education agenda, he received something of a history lecture about the persecution of blacks in America and the struggles of African American children to meet the academic achievements of their white counterparts.

Seeking to broaden his appeal heading into the general election, Romney was venturing for his first time in this campaign into an impoverished black neighborhood to hear the concerns of local educators and community leaders. But here in the streets of West Philadelphia, the emotion surrounding his contest with the nation’s first black president was raw, as dozens of neighborhood residents shouted, “Get out, Romney, get out!”

Romney arrived at Universal Bluford Charter School aboard his logo-emblazoned campaign bus and began his morning visit by meeting school and civic leaders at a formal roundtable session. “I come to learn, obviously, from people who are having experiences that are unique and instructive,” he said. […]

Outside, meanwhile, some brick row houses across from the school were boarded up. Police had cordoned off a full city block to protect Romney and his entourage. Residents, some of them organized by Obama’s campaign, stood on their porches and gathered at a sidewalk corner to shout angrily at Romney. Some held signs saying, “We are the 99%.” One man’s placard trumpeted an often-referenced Romney gaffe: “I am not concerned about the very poor.”
