FILE - In this Nov. 7, 2012 file photo, AFL-CIO President Richard Trumka, center, speaks with supporters at a union hall in Cleveland before a door-to-door campaign to urge a no vote on Ohio Issue 2. Unions spent $24 million to overturn the anti-union measure in Ohio, only to lose their effort to recall Wisconsin Gov. Scott Walker the following June. Blindsided by a new law weakening union rights in Michigan, organized labor is preparing to target Republican governors in politically important states up for re-election in 2014.
