McCain mentions JFK assassination during debate

McCain: Well, this has been a tough campaign. It's been a very tough campaign. And I know from my experience in many campaigns that, if Sen. Obama had asked -- responded to my urgent request to sit down, and do town hall meetings, and come before the American people, we could have done at least 10 of them by now.

When Sen. Obama was first asked, he said, "Any place, any time," the way Barry Goldwater and Jack Kennedy agreed to do, before the intervention of the tragedy at Dallas. So I think the tone of this campaign could have been very different.
