RENO, Nev. (AP) — In a high stakes election that could help determine the presidency and control of the U.S. Senate, attention in Nevada is turning this week to one option on the ballot with no shot of winning: None of these candidates.

A lawsuit filed in federal court in June and financed by the Republican National Committee seeks an injunction to boot the state’s unique voter option from the Nov. 6 ballot. Since 1976, every election ballot for statewide races, including president and U.S. Senate, gives voters the option to select “none of these candidates.”
