In other news, a large part of the population of the US knows nothing about politics.
So because they disagree with you that automatically makes them ignorant?
Certainly a large part of the US population is rather unaware when it comes to politics, but what does that have to do with this poll?
I said a large part, specifically because a) not all of this 51% falls into that category and b) there are quite a few on the other side of this question as well.
But seriously, Obama is more liberal than maybe 40-45% of Americans, so there has to be a sizable percentage that are just stupid.
