Recently, a poll came out from Gallup that caused a bit of a stir. For one, it showed Mitt Romney was 6 points ahead of the President. This was certainly different than pretty much every other poll that released during the same time.
The funny thing was, at first, only Fox News covered the poll. No other major news agency even mentioned it. At first I just chalked that up to the usual Left-Right media bias but then I noticed that indeed, no other polling agency had anything even close to Gallup's result.
So what's going on? Well I leave it to Nate Silver of the FiveThirtyEight blog:
