Both the Obama and Clinton headquarters opened in Philadelphia today, and Chelsea Clinton will be working for her mom on Penn campus. At 4:30 PM she’ll host an event called “Our Voice, Our Future” at Wynn Commons, 3417 Spruce Street.The Clintons have quite a bit of work to do. My general impression is Philadelphia is an Obama county. Certainly, it’s to the point where within a certain age range it’s not at all cool to support anyone else.Although I only work two doors down from this afternoon’s event, I much prefer to catch a timely train home rather than try to squish myself in with the collegiate crowds. If it were Hillary herself, sure. I’m sure Chelsea is a good speaker, but all I’d want to know from her is why she ditched Socks when they left the White House.
