Was it hurricane Sandy that won it for President Obama?

Many forecasted that Mitt Romney would defeat President Obama in the 2012 presidential election. They were wrong.

Some of those who were incorrect took it in stride and admitted as much. Others, such as Twitter sensation and National Review blogger Josh Jordan (aka NumbersMuncher), decided that their logic was sound, and it was only because of Superstorm Sandy that Obama won. …

The question is whether the polls indicate that Obama gained in the final days. We can figure this out by comparing pre- and post-Sandy pre-election surveys. [cont.]
