The death blow to the Republican party is the massive increase in Democratic registration for Obama. Registration is good for life unless you move. I am sure Obama will be a main campaigner for Democrats in the future so he will bring the Africans out who did not vote prior to his elections. These are different times. Plus you are dealing with a more educated electorate. But we will still take the idiot voters giving Trump the nomination. Makes the work easier.
For whatever it means, I am an Independent, but I never voted for a Republican President because I don't like wars and I do not support the military industrial complex.
