I’ll go along with Old Sarge. Here’s why.
While he held his first job after college (and apparently the only one in private sector, and for a short time) Obama wrote to his mother that he hated it because it was working for the enemy!
In his ghost written book, he confesses that during college years he was drawn to Marxist professors. These are documented admissions, and there may be others (I haven’t read his two books, and won’t read them) to illustrate Obama’s views and loyalties.
