I'm not anywhere near the first or last to comment on Barack Obama's rightward tilt since clinching the Democratic nomination, but I think there's a messaging opportunity here that may resonate well on Barack Obama: he is just another politician.
There is a subtle distinction here between this and calling him a "flip flopper." John Kerry ran a muddled campaign without a central message, and provided some absolutely golden soundbites that played into the notion that he was a flip flopper, so the attack really stuck. Say what you will about Obama, but he definitely has a message. Ironically enough, that could be his central weakness now.
Obama's entire campaign is based on the idea that he represents a new kind of politics, one which departs from the back-slapping, word-parsing, focus grouped, slippery politics of the past. There are hints of Jimmy Carter's "I'll never lie to you" campaign in 1976. So the notion that Obama is a slick used car salesman who will say anything to seal the deal cuts directly against his message of big ideas.
Today's Bob Herbert column compares him to Bill Clinton:
But Barack Obama went out of his way to create the impression that he was a new kind of political leader - more honest, less cynical and less relentlessly calculating than most.
You would be able to listen to him without worrying about what the meaning of "is" is.
However, the key distinction between Obama and Clinton in my mind is that Bill Clinton never really pretended not to be a politician. In fact, there was a sort of winking pride on Clinton's part in just how clever he could be. Obama, on the other hand, has spent more than a year telling us he'd lead us out of the politics of cynicism.
The most recent example is Obama's "refining" his position on Iraq, and newfound problems with partial birth abortion, but a great example is his decision to forego public financing. The "Declaration of Independence" from a "broken system," claims that somehow Republicans manipulate the public finance system, and that 527s are creature of the right (if only!) - a through the looking glass twisting of Orwellian proportions.
Bottom line, calling Obama a flip flopper is probably accurate, but suggests that Republicans have just dusted off the 2004 playbook. Calling him "just another politician" lances his central message right through the heart, and Mr. Obama has graciously provided us with prime examples. I suspect he will continue to do so through November.
