Obama: we're gonna cap greenhouse gases

By now I've heard Obama repeat the story in which he tells Detroit auto workers that they need to increase fuel efficiency at least 203948203948 times. Say what you will about it, but in his Wisconsin victory speech, he just announced his intent to cap and reduce the nation's carbon emissions. He's giving that speech in Houston.

Hillary Clinton, by contrast, tends to emphasize her love of domestic oil production when she speaks to crowds in Texas.
