The openers

From NBC's Mark Murray
Their opening remarks summarized the themes of their campaigns: Obama wants to bring the country together; Clinton is ready from Day One and is a problem solver.

Asked their policy differences, Clinton mentioned health care, home mortgage policy, and talking with unsavory leaders (she is against meeting with those folks in her first year in office).

Obama parried those differences -- and brought up Iraq and eliminating the influence of lobbyists.

So, far everyone is on message.
