FILE - In this March 16, 2013 file photo, Wisconsin Gov. Scott Walker arrives to speak in National Harbor, Md. As they gear up for re-election campaigns, many GOP governors, particularly those across the upper Midwest, find themselves in positions of strength, having benefited from improving economies if not changes of heart over their policies. Two years ago Walker faced angry crowds in the tens of thousands, vowing to oust him for signing legislation that stripped public employees of their bargaining power. Yet he attributed lawmakers’ closing a $3.6-billion budget gap to the measure, and won a dramatic recall election last summer by a wider margin than his 2011 victory. (AP Photo/Carolyn Kaster, File)
