Wow I think a rainbow tie would be a little more "nonpartisan" if you catch my drift. But this guy is ridiculous, we take the bias out? and he calls fox news not that bad, seesh. Also 80+% chance Obama will win dang. Also we already have jetpacks I think you could probably buy a jetpack for under 10,000 but I don't really know.

He takes the bias out mathematically. This is way oversimplified, but let's say for example a certain poll has historically over-favored Republicans by 3 points and under-favored Democrats by 3 points when compared to the actual results. So when he sees this poll release data for today that says "Obama 49, McCain 47", he can adjust this, or "take the bias out" by changing the numbers to "Obama 52, McCain 44". That's all he means, but of course his methods are much more complex.

And about Fox News not being that bad, he's only referring to their polls, as in, sure, they have a Republican lean, but they're not ridiculously skewed. There are polls that lean much more strongly Republican than Fox's polls. And Obama's chances of winning have greatly improved to 96.7%: http://www.fivethirtyeight.com.

Also, yes, we already have jetpacks, but I believe the implication was that they would be affordable and commonplace by 2036 (or whatever year he said -- I don't remember).

Nate Silver had the best record of anyone during the primaries at predicting the outcomes, even when polling was off. He is pretty trustworthy. Also, he admits that he is an Obama supporter who tries not to be biased instead of pretending to be completely neutral.
