Last year, McCain and Obama agreed to go with public financing in the general if they were the nominees, and now McCain is demanding that Obama adhere to his so-called pledge.
Obama is in a no-win situation right now, and it may very well not be his fault.
It appears that the argument regarding the “pledge” is that he made some inquiries regarding going on public financing in the general seem to be statements that have some wiggle room, but considering how far the press has their tongue up McCain’s asshole, it will be sold as a pledge.
I think that a good plan of attack against this is to show how McCain attempted to use public financing as an insurance policy for his campaign, where it would only kick in if he lost to retire his debts.
