Obama can not win Herman Cain, because he would take 5 to 10 per cent more of the black vote.
Also If Cain, or any black, Hispanic, or woman became the Republican President, they would lose some of their base forever and if the Republican don't have one of these as their nominee, they will never win another Presidential election after 8 years, the demographics don't lie.
That is why the dems will never let or any black, Hispanic, or woman became the Republican President and will kill to make it so.
Or dry ice.
Great!! And what is dry ice always used for?
Special effects.
