If Barack Obama somehow beats McCain, how long do you say it is until he gets inated?

Let's be honest, we live in a racist country no matter how much some people try to dismiss racism as a thing of the past. There's no way the white supremacists in this country would stand for their beloved country to be run by a black man, even if he's only half. It would be a radical redneck extremist or a puppet used by an undisclosed government agency that would take him out. One other reason would be his plans of what he wants to do when he's President. He clearly has unique views that attract a lot of people. He's different from Nixon, Reagan, Bush (both of them) and Clinton, and their corrupt administrations. Sadly, those views are shared by a lot of citizens but not by the rich and elite who really run this country. Caroline Kennedy said Obama reminded her of her father. Well, we all know what happened to him. So my question is not if he would get inated, but how long would it take?
