Oklahoma held primaries (for office other than President) on June 28. The Libertarian Party had a primary race for U.S. Senate. The tentative results: Robert T. Murphy 1,537; Dax Ewbank 1,073. The result was a surprise, since Murphy had been offered a job on the Gary Johnson presidential campaign, and so had asked voters to vote for Ewbank. But, Murphy has run for office many times during the last 40 years as a Libertarian, and when voters don’t know much about candidates, they are most likely to vote for a familiar name.
