President Obama suggested this evening that the Republican governing agenda will lead to "poisoning our kids" with pollution.

"I believe that it is part of our solemn responsibility to future generations that we look after this planet; that we make sure our air is clean and our water is clean; that we’re not poisoning our kids," Obama said at a campaign fundraiser tonight. That credo came as he explained that "the contrast between visions in this election could not be more stark, because I believe that America is stronger when we’re looking for one another."

Obama's line evokes his Associated Press speech this week, when he said Republicans believe that if the government "let businesses pollute more and treat workers and consumers with impunity, that somehow we’d all be better off." Mitt Romney, at his Associated Press luncheon speech, dismissed Obama's "rhetorical excess."

White House Press Secretary Jay Carney called that AP speech a "wonky . . . policy speech," but has been refashioned by the campaign into an attack video and a fundraising speech.
