Comedy host Stephen Colbert thrust the term "Super PAC" into America's headlights by mocking the groups known for funding political candidates, so long as they're not "coordinating" with the candidates. Mitt Romney supporters formed a Super PAC that's brought in over $30 million, and Newt Gingrich's Super PAC helped fund the ads that fueled his South Carolina win. So how powerful and effective are Super PACs? Is the one with the most money the key to winning an election? And how will funding from Sheldon Adelson and other Las Vegans turn the tide of the election and the face of Super PACs?
