I voted for Barack Obama in 2008. I had just turned 18. Soon after, I was surprised to find that paradise had not been brought about (ok I'm exaggerating, but only slightly). I then started considering conservative arguments put forth mainly by Dinesh D'Souza, Thomas Sowell and Milton Friedman. I was "mugged by reality."
D'Souza's book "The Roots of Obama's Rage" was the last nail in the coffin of my faith in Obama. Not only was I wrong in thinking that Obama's policies would restore/increase American greatness, I was deceived by him about his true intentions for America, his true ideology, his core beliefs, his "inner compass" as D'Souza puts it.
To this day, considerable mystery surrounds the man. Liberals and conservatives alike often find his behavior confounding.
In my view, the only one who has lifted the curtain on Obama is Dinesh D'Souza. It turns out our president has written an autobiography, and D'Souza read it! It seems to me like he's the only one sometimes. In "The Roots of Obama's Rage" and more recently "Obama's America" (also the documentary that was produced by Gerald Molen, 2016: Obama's America) D'Souza digs into Obama's past. It seems that Obama got his worldview/ideology from his father and mentors like Frank Marshall Davis. His father saw the colonial, exploitative West as the source of his and his country's (Kenya) problems. He was an anti-colonialist, he saw America as a rogue nation.
Maybe we're reluctant to dig into Obama's past because it leads to Africa, to race, to thinking about the "black man" and his exploitation by the "white man." These are "no-go" zones (taboo) for many of us. But we must understand Obama if he is to be defeated in 2012.
A good introduction to D'Souza's ideas about Obama:

(I know it's Glenn Beck, but D'Souza presents his ideas well here I find)
