As the following two clips highlight, I think this could be Obama's gas tax holiday moment: as in the primary, he needs to repeatedly hit McCain and the GOP hard for their gimmickry and ignorance.
Like the gas tax holiday, deriding the filling of tires at first blush sounds good, but once you start thinking about it (or hear Barack talk about it), you realize you're being played. And just as the gas tax pander failed with voters during the primary (data here), this will too if it's continued to be handled the right way.
And here's the expanded version of Obama's response shown at the end of previous clip. It's a great counter to McCain's stupidity.
So what do you think? Is this Obama's gas tax holiday moment? Will it help him turn the momentum back to Barack right before politics goes on an Olympic holiday?
