The dictionary definition of radical is of or going to the root or origin; fundamental: a radical difference. Generally speaking, a radical person is somebody who makes a difference, and that's why Obama is the President of the United states. So when you watch Newt Gingrich rant on national television about how Obama is the most radical president the US has ever had, he is essentially saying that the United States would have to be off its rocker, to fail to grant this radical president, a second term.

Morons like Newt Gingrich are caricatures. In a desperate attempt to say something deragotory about Obama (because Gingrich is a partisan bigot who has nothing nice to say about democrats) he in fact promotes the best reason to vote for Obama in 2012. Thanks Newt.
