FILE - In this March 1, 2013 file photo Michigan Gov. Rick Snyder speaks in Detroit. 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. Snyder inflamed the state’s shrinking labor vote in December, when he reversed course and signed legislation, stripping unions of their ability to force employees to pay dues. Since then his job approval has risen, a reflection of improving jobs numbers: in April unemployment was 8.4 percent, down from 11 percent in 2011. (AP Photo/Paul Sancya, File)
