Tennessee held partisan primaries on Thursday, August 7. Republican State Senator Jim Summerville was defeated for re-election. He placed third in a four-way primary race. On August 11, he announced that for the remainder of the term, he is no longer a member of the Republican caucus and that he should be listed as an independent. He is serving his first term. See this story. Tennessee does not have registration by party, so the only indication of anyone’s affiliation is what he or she says publicly. Thanks to Michael for the link.
