Obama is a T-R-A-I-T-O-R.
But, how does he have so many followers?
Public school “education”.
Having watched my high school senior daughter's history curriulum since first grade, it's pretty clear what the answer to your question is.
Fortunately, I have always been able to provide her with a counter perspective, which is why she is now a very passionate conservative.
But most of her skull-full-of-mush classmates have absorbed the official party line and adore Obama, as do most of their teachers.
