Remember: this is the candidate who’s supposed to be taking us away from the politics of negativity. Unless you disagree with his math, of course: then you’re just being proudly ignorant.

But he still wants your vote! – Moe Lane}

Obama in Ohio:

Let me make a point—let me make a point about efficiency, because my Republican opponents? They don’t like to talk about efficiency. You know, the other day I was at a townhall meeting, and I had laid out my plans for investing $15 billion a year in energy efficient cars and a new electricity grid and all this. Somebody said: well, what can I do, what can individuals do? So, I told them something simple. I said, you know what, you can inflate your tires to the proper levels, and that if everybody in America inflated their tires to the proper level we would actually—probably save more oil than all the oil we’d get from John McCain drilling right below his feet there, wherever it is that he was going to drill.

So, now the Republicans are going around—this is the kind of thing they do, I don’t understand it—they’re going around sending, like, little tire gauges, making fun of this idea as if this is Barack Obama’s energy plan.

Now, two points. One, they know they’re lying about what my energy plan is. But the other thing is, they’re making fun of a step that every expert says would absolutely reduce our oil consumption by three to four percent. It’s like—it’s like these guys take pride in being ignorant, you know? They think it’s funny that they’re making fun of something that is actually true. They need to do their homework. Because this is serious business. Instead of running ads about Paris Hilton and Britney Spears, they should go talk to some energy experts and make a difference.

But the problem isn’t that Republicans denied that air pressure could save fuel. The problem is that Obama’s math was way off. Powerline did the math, Jim Geraghty did the math, and Jake Tapper [did the math] (http://blogs.abcnews.com/politicalpunch/2008/07/from-the-fact-1.html), and under no scenario do you get to savings equal to offshore drilling.

So who is ignorant and who needs to talk to the experts?
