On December 1, the Tennessee State Executive Committee passed a resolution in favor of changing voter registration forms, to ask voters to choose a party. This would enable parties that have primaries to close them. See this story.
The party also endorsed raising the number of signatures for independent candidates. Currently all candidates need 25 signatures, except presidential independents need 275. The resolution recommends 1,000 for statewide office; 500 for U.S. House; 200 for State Senate; and 75 for State House. County offices would still need 25.
