I like to think it's because he was CEO of something so at least has some idea of what it takes to run a private sector business...also, he actually appears genuine, not some slick spin BS machine like our current POTUS and Rick and Mitt (who I get the feeling would say or do anything to achieve POTUS whether it was true or not, right or wrong).
To be honest this field is somewhat weak (and the probable gop nominee should beat Obama) so that may have something to do with it but Cain is a rising star in the Republican Party. People like him for his conservative ideals. A lot of Democrats (liberals) voted for Obama simply to prove they weren't racist.
But simply showing they aren't racist is what a racist does : judging a mans skin color instead of judging him by his deeds and character.
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.
