He noted how Obama, in Dreams from My Father, stated that when he got to college, he attended 'socialist conferences' and 'hung out' with Marxist professors. But what Obama did not explain or clarify, says Dr. Drew, is that Obama 'was in 100 percent, total agreement with these Marxist professors.'" ~ Paul Kengor, Professor of political science at Grove City College.
Well, not any historian. Some do ignore. Why did so many academics endorse Barack Obama for President? Why did they choose to ignore Obama's Marxist mentors? Just more anecdotal evidence coming from a reactionary "outside of academia" I suppose. No, wait, this was written by an academic!
