FILE -This June 25, 2012 file photo shows Wisconsin Gov. Scott Walker speaking in Chicago. When Maggie Hassan won the New Hampshire governor's race, it wasn't just a victory for Democrats. Unions spent millions to elect Hassan because she can block a Republican legislature from gutting their organizing and bargaining ability. From California to Maine, unions used their political muscle to defeat ballot initiatives against them and elect labor-friendly governors and lawmakers. (AP Photo/Charles Rex Arbogast, File)
