On race, Barack Obama often says he is not president of black America, but of the United States of America. Though he has not avoided the subject during his time in office, he tends not to seek out opportunities to discuss racial issues.

"He wanted to address them in a time and a way that accomplished specific objectives," says Joshua Dubois, who ran the White House's faith-based initiatives during Obama's first term.

The Republican ticket of Mitt Romney and Paul Ryan campaigned in northeastern Florida on Friday, where thousands of men had descended on Daytona Beach for the annual motorcycle festival Biketoberfest.

A bunch of them were at Willie's Tropical Tattoo smoking cigarettes, drinking beer and listening to music.

During the Republican National Convention last month, I traveled with Mitt Romney's campaign from Tampa, Fla., to the American Legion conference in Indianapolis.

Romney delivered a speech about foreign affairs and national security. Among the thousands of attendees from around the country, I interviewed one woman from Virginia whose quote sparked a conversation among NPR's audience and staff.

Republican presidential candidate Mitt Romney campaigned outside of Philadelphia and Pittsburgh on Monday, a day before Pennsylvania and four other states hold their primary contests.

Romney isn't concerned about the primary, but Pennsylvania will likely be an important swing state in the general election. And Monday also offered a chance to audition a potential running mate: Florida Sen. Marco Rubio.
