Obama brings a gun to a knife fight

The McCain campaign and RNC are pouncing on another line from the Obama pool report:

“If they bring a knife to the fight, we bring a gun,” Obama said in Philadelphia last night. “Because from what I understand, folks in Philly like a good brawl. I’ve seen Eagles fans.”

McCain and the RNC took on the comment in terms that will be very familiar to people who followed Clinton campaign statements last year:

“Barack Obama’s call for ‘new politics’ is officially over. In just 24 hours, Barack Obama attacked one of America’s pioneering women CEOs, rejected a series of joint bipartisan town halls, and said that if there’s a political knife fight, he’d bring a gun," McCain spokesman Tucker Bounds said, referring also to the Obama campaign's shot at Carly Fiorina's lavish pay package and role in layoffs at Hewlett-Packard.

“Why is Barack Obama so negative? In the last 24 hours, he’s completely abandoned his campaign’s call for ‘new politics,’ equating the election to a ‘brawl’ and promising to ‘bring a gun,' " said the RNC's Alex Conant.

Obama doesn't actually use the phrase "new politics" a lot, and this is a box that the Clinton campaign tried, and failed, to keep him in last year, when it emerged early that he was happy to throw punches, and even to start fistfights, sending, for instance, the first negative mail to hit in Iowa last fall.

Obama never paid much of a price for his willingness to go negative. He also, to be fair, never promised that he wouldn't attack, and indeed often promised to be tougher than past Democrats, and bragged of his Chicago training. He disavowed nasty character attacks, but then everybody disavows nasty character attacks.

What's left of course, is to speculate on what form of political change Obama promises: It's not some sort of disarmament; it's not any large deviation from traditional Democratic policy; it's more a vaguer — and harder to control, and deliver — promise to lead the country past the deep cultural divisions around race, religion and even Vietnam that have dominated national politics for decades.
