Several states with competitive Senate races saw their unemployment numbers drop in April, but that trend was bucked by Nevada, where Senate Majority Leader Harry Reid (D) faces low approval numbers and is a top target for Republicans. Unemployment in Reid’s state, one of the hardest hit by the housing crisis, jumped from 13.4 percent in March. The state had 40,000 fewer jobs in April 2010 compared to April 2009, according to statistics released Friday by the Bureau of Labor Statistics.
