The union opponents of the November ballot initiative to make Colorado a "right to work' state went to court today to try to throw the initiative. The court case alleges "massive" signature fraud, with so many duplicates and false signatures that the measure could not have properly qualified for the ballot. Such suits are common and usually get thrown out. But the political climate in Colorado is so hostile to direct democracy and signature gathering now that if I were a backer of the "right to work" measure, I'd be worried.
