6-5-12  --  Wisconsin voters decide today whether their governor, Scott Walker, stays in office -- or gets the boot.  The recall effort has attracted lots of attention from Minnesotans.  Minnesota labor unions have been helping the dump-Walker campaign.  They call the conservative Republican governor an enemy of organized labor after he and Wisconsin's GOP legislature sharply curtailed collective bargaining. But that's made Walker a hero to many others, including Kurt Bills, the Minnesota Republican endorsee for U-S Senate.  Bills scheduled an election eve visit to Wisconsin to help bolster Walker's chances.  Latest polls show Walker a slight favorite over Democrat Tom Barrett.  It's a high stakes political contest for both parties.  The campaign spending has been high stakes, too -- in total, more than 63-million dollars.
