Secret Ballot - S1.E24

Randall's old war buddy Ned Easter is running for mayor in a town governed by corrupt mayor Barney Pax and his brother Steve, whom he has made sheriff. The Pax brothers avoid honest competition by shooting up Ned's rallies and such. Ned's wife Carole has summoned Randall to stand by Ned in case of trouble, but doesn't want Ned to know she did so. It so happens that Randall has a wanted poster on Steve, for ""shooting up half of Colorado.""
