The independent political groups known as super PACs have been super busy in Florida. So far, they've spent more than $44 million on the presidential race, according to an estimate by the Center for Responsive Politics.
That is more than four times as much compared to this point in the 2008 campaign.
Turning the tide on ad spending by these independent political action committees, Massachusetts' Republican Senator Scott Brown and his leading Democratic challenger, Elizabeth Warren, have agreed to discourage super PACs from taking sides in that state's Senate campaign, after outside groups backing each candidate had already begun launching seven-figure ad bursts.
When asked on "CBS This Morning" if there is need to control super PACs, Brown replied, "I can only speak to my campaign. I called for this last election, I called for it this election. I'm glad Professor Warren wanted to join with me."
Brown, explaining how his pact with Warren works, said that if "a super PAC comes in and runs a positive or a negative ad for my benefit, I would then have to pay one-half of that ad buy to the charity of the other person's choice. So that's the teeth.
"So these people can certainly come in, but just know they're going to hurt the individual candidates," he told Charlie Rose.
And despite their prevalence in the GOP presidential primaries so far, Brown isn't anxious for them to contribute to his reelection race: "I find mostly they're false and misleading," he said. "We can talk about our own records - or lack thereof - on our own."
And they have plenty of resources to do that. According to the Boston Globe, Warren's campaign has at least $6 million in her campaign account, while the incumbent Brown has $12.8 million.
When it comes to the use of super PACs in the presidential race, Brown said, "I'll leave that up to the candidates that are running. I know that in my race, in Massachusetts, I think the voters deserve better. We came up with a plan, I think it's a good plan, and I'm hopeful that she'll stick to it, and I'm looking forward to obviously running a very clean campaign like I did last time. But I'm also going to draw a line in the sand and stick up for my record."
