A.P. offers this report, which begins: “The Kansas Republican Party chairman had no authority to open the Aug. 3 primary to independent voters, a district judge ruled Wednesday. Judge Charles Andrews ordered Secretary of State Ron Thornburgh not to allow independents to vote in the primary, as directed by state chairman Dennis Jones on June 4.” The article suggests a constitutional challenge was not properly before the judge. A constitutional challenge should be successful under Tashjian and California Democratic Party v. Jones, which give parties the right to object to the form of primary put in place by the state.
UPDATE: Ed Still explained here that the problem was that the GOP apparently did not vote properly to include the independent vote.
