Campaign ads: Obama and Clinton debut new Pennsylvania spots as polls tighten

In their latest spots, both of which hit the air yesterday in Pennsylvania, Hillary Clinton goes for sentimentalism and Pennsylvania ties, and Barack Obama courts the female vote.

Polls from the state are all over the place — an 18-point lead for Clinton in new SurveyUSA numbers released yesterday, a 45-45 tie in ARG data from just days before — but as Pollster.com’s chart reveals, there’s been a decided tightening of late.

Barack Obama: Maya (:30)
