National unions have put more than $1 million into Colorado, mostly to fight the right-to-work initiative that recently qualified for the ballot. SEIU, the nation's largest union, has donated more than $600, and things are just getting started. This Denver Post story predicts that the right-to-work initiative will cost more than $25 million, and the ballot will have more than a half-dozen measures. Look for Colorado, not Ohio, to be the biggest swing state this fall, as presidential contenders battle over it, and the forces of business and labor from across the country attempt to bloody each other with initiatives here.
