Defining Moment for Democrats?

Round seven in the Democrats' drumbeat of presidential debates was a slugfest last night. The prime target: frontrunner Hillary Clinton. The attackers: just about everybody else on the stage.

The first primaries are just two months away now. No time to waste. Obama promised fireworks, but seemed mild on the attack. Edwards was on fire about Clinton's honesty and credibility. Dodd asked if she's really electable. Hillary stood strong, but this was tough criticism from inside the party.

This hour, On Point: on the Democrats' homestretch, Hillary Clinton feels the heat.Guests:
