Chelsea Clinton was a huge attraction Friday night as she toured some of Philadelphia's most famous gay nightclubs, reports Mathew Berger for MSNBC's First Read:

Chelsea Clinton stopped traffic Friday night as she wandered the streets of Philadelphia on a gay bar crawl, winning rave reviews for both her politics and her appearance.

Led around the neighborhood by Gov. Ed Rendell, Chelsea was mobbed by local gays and lesbians, as she walked from one club to the next. They ran up to hug her, posed for pictures and certainly invaded her personal space.

"I grabbed her ass," one young woman exclaimed to her friends after snapping a picture with her arm around the former first daughter.

"Chelsea, the gays love you!" one fan exclaimed, as she took the microphone at Bump, a restaurant and bar that was her first stop. "Oh, gosh, I don't know if everybody loves me," she responded.

What effect surrogate campaigning may have in Tuesday's Pennsylvania Primary remains to be seen. Conventional wisdom holds that Obama needs to roll up heavy majorities in the Philly area to offset Hillary's anticipated sweep of the more rural counties.

Obama has gone all in for PA, outspending Clinton by a reported 5 to 1 and closing the margin in most polls to mid-single digits. However, Hillary has shown the tendency to carry the late deciders by a strong margin (helping her confound polling in New Hampshire, California, and Ohio). Obama pointedly refused to hand out "walking around money" in Philly, which may hurt his turnout there. Traditionally, this is cash put out on the "street" to black community leaders to ensure the turnout, and there may be some resentment that the wealthiest political campaign of all time is so stingy.
