From the New York Times:
Gov. Rick Perry of Texas struggled through his first three debates, so his aides have staged practice sessions, complete with a stand-in for Mitt Romney. He has stirred outrage among conservatives on immigration, so he is defending his stance on the campaign trail as good economics.
And as he prepares for two more debates in the next nine days, along with his first major policy address, his advisers have devised another way to help: requiring Mr. Perry to get more sleep.
