If you're wondering how much money superPACs are spending in various primary states to influence the 2012 general election and where they're spending it, the journalism non-profit ProPublica has a useful tool for you, PAC Track.
The spending by Restore Our Future Inc., a pro-Mitt Romney superPAC, presently shows the huge money advantage Romney supporters have over supporters of his rivals for the Republican nomination. ROF by itself has pumped $5.1 million into Florida, according to the tool. The superPACs supporting the other candidates come nowhere close.
Winning Our Future, a superPAC supporting Newt Gingrich doesn't show up yet though that should change in a future update. Miriam Adelson, wife casino billionaire Sheldon Adelson recently announced a $5 million donation to WOF just in time to get ads on the air before next week's Florida primary.
