LAS VEGAS (AP) — Voters in the Colorado River casino town of Laughlin are rejecting cityhood.Laughlin residents turned out in larger numbers Tuesday than voters elsewhere in Clark County to reject the incorporation measure, 57 percent to 43 percent.The vote to become Nevada's 20th incorporated city revolved around whether the community's 7,000 residents would be better served by a local government, or by continuing to rely on a county administration that serves some 2 million residents.The city boundary takes in vast vacant areas generally south of State Route 163 between the California and Arizona state lines.Some in Laughlin say they pay too much in taxes to Clark County and for police protection from metropolitan Las Vegas, 100 miles away.State taxation officials say a city of Laughlin could double costs to taxpayers for animal control, planning, police, fire, parks and public works.
