Most likely a democrat, the republicans have not brought forth a decent candidate, a hispanic like Rubio could stand a good chance, but I doubt if he will get the support he needs. I think Americans would vote for a strong independent because they do not trust democrats or republicans at this point in time. 4 years is a long time off anything could happen, chances are Obama will leave a sour taste in voters for democrats, tax payers will probably have had enough.
History suggests a republican because since WW2 almost every time after a president has served two terms the next president is from the opposing party. Harry Truman Democrat 2 terms next President Republican Dwight D Eisenhower Served 2 terms. After Him DEmocrat John F kennedy.
Next two term President Ronald Reagan who was so successful that his Vice President was the next president for one term. After Bill Clinton a democrat served two terms George w Bush a republican had two terms and after him the current President Barack Obama a democrat is in his second and last term.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
