CHEYENNE, Wyo. (AP) — U.S. Sen. John Barrasso faces token opposition and Rep. Cynthia Lummis is unopposed in a Wyoming primary that also promises to keep Republicans dominant in the state Legislature.

Barrasso is a Republican who is running for re-election for the first time. His challengers in Tuesday's primary are Emmett Mavy, a management consultant, and Thomas Bleming, a self-described "soldier of fortune."

Democratic Party activists say Albany County Commissioner Tim Chestnut is favored to win that party's U.S. Senate primary.

Chris Henrichsen, a political science instructor from Casper, is unopposed in the Democratic congressional primary.

In state legislative races, Republican candidates far outnumbered Democratic contenders — a sign that the GOP will keep control of both chambers next year. Republicans outnumber Democrats 26-4 in the Senate and 50-10 in the House.
