Senators Barack Obama and Hilary Clinton are planning a joint appearance next week, according to published reports. They're expected to try and cool tensions among Democratic voters and more immediately, among Democratic donors. Still, relations between the candidates' camps remain unsettled.

For some insight into how Clinton supporters are leaning, we're joined now by longtime Chicago Democratic strategist, Delmarie Cobb.
