@McGentrix,
If I read this article correctly, Obama is an extreme lefty because a) he has a lefty background and b) because he voted with the Democrats on just about all issues. But what about the legislation he championed? Protection for Veterans' benefits? Bills to secure waste nuclear material? Protection from false confessions (Ill. state senate)? These aren't partisan bills. In fact, I think a lot of Republicans would love to say they sponsored them.
An even handed but critical review of Obama's record would say that he is more pragmatic than liberal. Saying he must be a lefty's leftist because he was exposed to other cultures and religions in his youth seems to be a silly argument when there is so much more to look at.
