LAS VEGAS — Nevada Gov. Jim Gibbons has been thrown out of office after a tumultuous term that was marred by a bitter divorce and allegations of infidelities. The first-term Republican lost the GOP primary Tuesday to former federal judge Brian Sandoval. Rory Reid won the Democratic primary, earning a spot at the top of the ballot next to his senator father. Gibbons is the latest incumbent to be ousted this election year.
