Polls and their methodology have become an interesting topic over the last few days, as we had one PD reader ask us how the heck does the “average Joe” understand what’s going on?

The main argument is that many of the media polls are oversampling Democrats in their polls, and that this methodology is skewing the polls towards the President. One site, unskewedpoll.com, goes as far as giving Mitt Romney a seven to eight point lead in the national polling.

This skewing is being addressed by both pundits and the Romney campaign.

Here’s a clearer explaination of how the polling data seems to skew towards a more Democratic voting base.

Is the nation trending towards more registerted Dems, or are the polls being manipulated?
