Senator and Democratic presidential hopeful Barack Obama (D-IL) responds to a question from CNN's Wolf Blitzer about an earlier comment made by opponent Sen. John McCain (R-AZ) saying that Hamas would vote for Obama.

"This is offensive," says Sen. Obama, "and I think it's disappointing, because John McCain always says 'Well, I'm not going to run that kind of politics.' And then, to engage in that kind of...smear, I think is unfortunate."

Obama insists his Hamas policy is identical to McCain's in that he considers them a terrorist organization and says the US should not negotiate with them unless they recognize Israel.

"For [McCain] to toss comments out like that, I think, is an example of him losing his bearings as he pursues this nomination."
