Item: Democratic presidential contest turns to Pennsylvania/Associated Press

More Info: A six-week, increasingly hard-edged Pennsylvania primary contest between Democrats Hillary Rodham Clinton and Barack Obama culminated today as voters registered their choice — a decision that could save or sink Clinton’s flagging candidacy. The candidates questioned each other’s character and readiness to be commander in chief in last-minute television ads and barnstormed the state in a final pitch for votes in the most populous and delegate-rich state remaining in the nominating contest. Some 4 million Democrats were eligible to cast ballots, with 158 delegates at stake.

Question: Who will win the Dem primary in Pennsylvania and by how much?
