47 percent

Well we are 40 days away from Election Day here in the U.S. And there's some new polling about just how much a voter's income determines his or her vote.

Frank Newport of Gallup drops by to school us on just what factors truly effect how we vote for the president. Spoiler alert: gaffes like Romney's "47 percent" aren't one of them.

Mitt Romney wasn't wrong when he said almost half of Americans don't pay federal income taxes. Some of those people are retired, some are poor. Another big reason why some don't pay? Tax cuts.

Republican presidential candidate Mitt Romney says 47 percent of Americans pay no net income tax -- ergo, they are predisposed to vote for President Obama. We break down the numbers.
