GhaleonEB said:Bear in mind that Obama has been successful at stymieing funding for many (but not all) 527 groups, true to his word. McCain has given his 527's free reign. If Obama took public funds, this alone would put him at a huge disadvantage. It would mean he would either have to go back on his word about reigning in 527s in order to balance things out (which really would be breaking a pledge), or ceding a major advantage to McCain. Which he's not willing to do (understandably).
Of course this benefits him by leveraging his formidable fund raising network, but it's not the broken pledge you and others are making out to be.
From what I've read, not a single significant pro-McCain 527 has even emerged. Obama is going to have an absolutely huge huge money advantage, whether any 527's come out of the woodwork or not.
Edit- as the AP reports, Obama is actually the candidate that has had outside help with ads already.
