My prediction, posted here many times, is that the next General is the democrat's to lose, whether Hitlery or someone else.
Also, the Republican Party is hell-bent on self-immolation, so they will nominate a RINO, and lose.
The only possible way for the Republicans to win is to nominate a constitutionalist, such as Ron Paul. He is the only one who actually would stand a chance of winning.
But don't worry yourself any; Dr. Ron Paul will not be the Republican nominee.
