On July 20, a Tennessee state trial court ruled that the Democratic Party is allowed to block a candidate from its primary on the grounds that the party doesn’t believe the candidate is a bona fide Democxrat. Elizabeth Stephens wanted to run for U.S. House, 5th district, but the party had rejected her. She sued but did not win the lawsuit. See this story.

Tennessee does not have registration by party. The voter registration does not ask about party membership.
