STATE COLLEGE, Pa.— If the numbers are to be believed, the rallying chants of "Yes, we can!" echoing across Pennsylvania State University's campus on a recent Sunday afternoon may be more than just rhetoric for Barack Obama. Weeks of his hard campaigning, growing superdelegate support, and surge in fundraising appear to have chipped away at Hillary Clinton's comfortable lead in the Pennsylvania polls and thrown her presumptive victory April 22 into doubt.

For Obama to pull off the upset, he will need the help of voters like Don King, a 64-year-old retired teacher from Montoursville, Pa. King, a lifelong "Eisenhower-type" Republican, his wife, and his son-in-law are a few of a record number of voters who switched parties.
