WASHINGTON (AP) — Unemployment rates fell in 24 U.S. states last month, including some of those with early presidential nominating contests. The unemployment rate in New Hampshire, site of the second contest, slipped to 3.7 percent from 3.8 percent. Economic issues occupied a small portion of the GOP's first presidential primary debate last month, a stark contrast from the primary debates of 2012, which focused heavily on jobs and the economy. West Virginia, which has been hit by a steep decline in coal prices, has the highest rate, at 7.5 percent.
