According to Newt Gingrich, (a) we "discovered" fracking by drilling for it, (b) biofuels made from algae are ridiculous, (c) we can solve our oil problem by drilling for natural gas, (d) we can totally get gasoline down to $2.50 a gallon, and (e) if Iran screws with the Strait of Hormuz we should invade their country. Or possibly just nuke them. He wasn't real specific about that. And that was after calling Barack Obama "incoherent."
Also: this was just in the three or four minutes of his speech that I listened to. Holy cow.
