The president could easily turn that around on the GOP by rightly blaming it on speculation and calling for reforms in commodities trading and then watching the republicans close ranks around their Wall Street friends showing the thing they really care about most.
Wall Street...Yes. The very same Wall Street you guys are crowing about because Obama is causing the Dow Jones Industrial Average to climb. Wall Street...The same people who helping to fund Obama's campaign. That's right, Wall Street people are handing Obama money like they weren't going to make any more.
And BTW, Obama has had plenty of time to order up new regulations on commodity speculating, but chose to sit on his hands. Why? Because it was politically prudent for him to do so!
