The 2012 Presidential election looks like it will be the most expensive race in history. Between the campaigns, the national committees and the super PACs, billions will be poured into TV ads, polling, and staffing. So far, the Obama campaign has outspent Romney’s but that’s not counting all the spending by pro-Romney super PACs, powerful groups like American Crossroads and Restore our Future, who are funneling money into anti-Obama attack ads. This hour, we’ll look at how money is driving the 2012 race for the White House and how it’s affecting the political process. Marty talks with DAVE LEVINTHAL who covers the political influence issues for Politico.
