Barack Obama has opted out of public financing for the general election stating “the public financing of presidential elections, as it exists today, is broken — and the Republican Party apparatus has mastered the art of gaming this broken system” in his USA Today Op-Ed. John McCain will likely try to make this an issue, since Obama once said he would use public financing if his opponent did and John McCain has opted in.
The maps below show the fund raising edge that Barack Obama has over John McCain that certainly was a motivating factor in opting out of the public financing funds. Barack Obama appears to be raising more than John McCain everywhere, including Republican strongholds such as Texas and the South. McCain looks to only have a fund raising advantage in his home state of Arizona.
