Feb. 27, Headlines - For the 20th time, Hillary Clinton and Barack Obama debate. This time in Cleveland, Ohio, just one week before voters in four states, that state as well as Vermont, Rhode Island, Texas vote or caucus.

Clinton and Obama supporters rallied outside as did about 100 anti-war protesters.

Columbus Ohio station WCRS reporter Eugene Beer gives this description:

"Just outside the debate hall, we have protesters on both sides of the corner. I would estimate about a hundred or a hundred fifty people."

Inside the debate hall, the mostly cordial yet accusatory Clinton and Obama challenged each others policies on trade and health care.

On foreign policy, Clinton pointed out some of Obama's past statements.

"Obama basically threatened to bomb Pakistan. I don't think that is a particularly wise position to take."

Clinton has not denied that she would take such action but that she would not discuss such options publicly. Here's Obama's response.

"If we have actionable intelligence against Bin Laden or other key Al Qaeda officials and Pakistan is unwilling or unable to strike against them, we should."

That was the last scheduled debate between the two.
