Tennessee special election stirs Democratic hopes and GOP fears of an upset

Tuesday’s special election in Tennessee’s 7th Congressional District, normally a conservative stronghold, is giving Democrats hope that their recently successful message of affordability can help them spring a major upset. The contest pits Trump-backed Republican Matt Van Epps against Democratic state Rep. Aftyn Behn. The winner will replace former Rep. Mark Green, who resigned in July.
