What will the likes of the Swift Boaters cook up as attacks this election year?

The 2008 election was full of Big Lie attacks launched by Jerome Corsi of 2004 Swift Boat and Birther fame, Dick Morris, Fox News’ Roger Ailes and a host of similar right wing propagandists. With Fox News and the vast right-wing noise machine to spread the lies even after they are thoroughly debunked, as they did so effectively in 2008; and with Citizens United providing perhaps billions in corporate funding and right-wing billionaire contributions to Super PACs, how far will it go? Is it possible to get so ridiculous lies and smears that it backfires?
