The biggest never-mind yet: that pledge about public financing. It is fine to say “little people” are funding his campaign, but so are Tony Rezko bundlers. It would, of course, be ridiculous for Barack Obama to give up his fundraising advantage. On the other, doing something not in his own self-interest would allow Obama to demonstrate his bona fides as the architect of New Politics. Will John McCain make some hay? Only if he is able to demonstrate a larger theme of “phony Agent of Change” can he make any headway on this. After all, campaign finance reform — despite McCain’s best efforts — was never an issue to seize the popular imagination.
