O'bama is a Democrat along with Hillary, so it will be quite impossible for them both to be the the front runners. More likely one Democrat against one Republican.
I'm voting for some other candidate like Ron Paul instead of 2 sides of the same evil coin. Both will be whores of the Drug companies and big business or they will be locked out of the election. Hillary will be for partial birth abortion but will fight to the death for a convicted murderer to be spared from execution. Democrats will increase taxes on the rich and poor. Republicans will embezzle from them.
