JEFFERSON CITY, Mo. (AP) — The steady march of new right-to-work laws in Republican-led states hit a wall in Missouri, where voters resoundingly rejected a measure that could have weakened union finances after national and local labor groups poured millions of dollars into the campaign against it. Missouri's law against compulsory union fees was defeated Tuesday by a 2-to-1 margin, nearly a year after the measure adopted by the state's Republican governor and Legislature had been scheduled to take effect.
