A lawsuit is challenging Election Day voter registration in Illinois while prompting concerns from civil rights groups about voter access in the November election. The lawsuit, filed in federal court last month by the legal arm of the Illinois Policy Institute, argues that voters in all 102 counties don't have equal access to same-day registration so it should be abolished at the precinct level.
