The Latest: Wyoming US Senate candidate withdraws late

CHEYENNE, Wyo. (AP) — The Latest on Wyoming's primary election (all times local):

9:40 a.m.

In an unusual move, one of the Republican candidates for Wyoming U.S. Senate seat has withdrawn from the race.

Charlie Hardy withdrew has application for the Republican Party nomination on Monday afternoon, less than 24 hours before the polls opened Tuesday.

Hardy was one of five challengers seeking to unseat incumbent John Barrasso.

But Hardy was never seen as a serious challenger in the primary. He had switched his party affiliation after running unsuccessfully for the Senate in 2014 as a Democrat against Mike Enzi and advocated for policies that were far more liberal than other candidates.
