Big, big endorsement for Obama
Pennsylvania's Democratic U.S. Senator Bob Casey -- now for Obama. Casey will join Obama on his six-day bus tour around the state -- his first stretch of serious campaigning in Pennsylvania.
I can't say how much this will mean at the polls, but when I used to live in Philadelphia, Senator Casey's father was very popular. More importantly, this is evidence of a growing trend of superdelegates closing ranks behind Barack Obama.
