The leaders of the Illinois Legislature are hoping to pass legislation that would allow illegal aliens to get a driver's license. In support of that effort, the senate's Assistant Republican Leader and a high-profile sheriff wrote an op-ed for a suburban Chicago newspaper, the Daily Herald, on Wednesday. State Sen. Bill Brady and Lake County Sheriff Mark Curran argued that the legislation would reduce the costs of uninsured claims. But a recent study by the Insurance Research Council squashes that argument.
