Iowa is awash in millions of dollars of negative campaign ads funded by so-called Super PACs as voters head to their caucuses in the first real test of the 2012 election. “If you want to see the future of politics in America, turn on the television in Iowa,” says John Nichols, correspondent for The Nation magazine. “If it is this kind of overwhelming flood of negative ads, literally flipping on a dime to take down any candidate who rises in opposition to the mainstream or kind of core Republican contender with the most money, it’s a pretty scary picture. And it is one that suggests that if we don’t get serious about addressing Citizens United [v. Federal Election Commission], we’re going to end up with a much uglier, much more destructive politics.” Nichols estimates the candidates and their PACs spent $200 per vote in Iowa. The latest public opinion polls show former Massachusetts governor Mitt Romney holding a narrow lead of 24 percent over Rep. Ron Paul and Rick Santorum. Nichols says Santorum’s comments over the weekend about not wanting to “make black people’s lives better by giving them somebody else’s money” highlight how Republican candidates have failed to reach out to Iowa’s many minority communities. Meanwhile, the Occupy movement has tried to inject the voices of the 99 percent into the race by holding protests at events and both Republican and Democratic campaign headquarters throughout the state.
