It never ceases to amaze me how little leftists know about American history. It's easy to explain though. They get all their historical facts from a liberal MSM, liberal movies, liberal teachers and professors, liberal books, and liberal TV shows. When you put "liberal" in front of any subject it means that the subject is guaranteed to be factually challenged. Leftists don't realize their brainwashing themselves so they never know the real facts about anything.
By the way, Michele Bachmann knows her history.
