May Day, Murdoch and the murder of Milly Dowler. What do they have to do with the 2012 U.S. general election? This year's election will undoubtedly be the most expensive in U.S. history, with some projections topping $5 billion. Not only has the amount of spending increased, but its nature has as well, following the 2010 U.S.

The Republican caucuses in Iowa, with their cliffhanger ending, confirmed two key political points and left a third virtually ignored. First, the Republicans are not enthusiastic about any of their candidates. Second, we have entered a new era in political campaigning in the United States post-Citizens United, the U.S. Supreme Court decision that unleashed a torrent of unreported corporate money into our electoral process. And third, because President Barack Obama is running in this primary season unchallenged, scant attention has been paid to the growing discontent among the very people who put him in office in 2008. As a result, the 2012 presidential election promises to be long, contentious, extremely expensive and perhaps more negative than any in history.
