(AP) -- In Nevada's primary election, Republicans will pick nominees in hotly contested races for lieutenant governor and the 4th Congressional District and Democrats will choose between eight relative unknowns hoping to mount an unlikely campaign to unseat popular GOP Gov. Brian Sandoval.
Light turnout was reported during early voting and election officials predicted the same at the polls Tuesday partly because Sandoval faces only token primary opposition and none of the Democrats is expected to seriously challenge him in November.
The spotlight is on the GOP race for lieutenant governor, where state Sen. Mark Hutchison enjoyed Sandoval's backing but ex-U.S. Senate hopeful Sue Lowden won the Nevada GOP's formal endorsement.
Republican Assemblyman Cresent Hardy and Niger Innis, a former tea party strategist, are bidding for the 4th District seat held by Democratic Rep. Stephen Horsford.
