Tennessee Republicans who are battling for the GOP nomination to replace former Rep. Mark Green all have the same platform: supporting President Donald Trump’s agenda. However, only one, Matt Van Epps, has the president’s endorsement, setting the stage for a temperature check on how much weight Trump’s backing carries.

The special election primaries to replace Green, who resigned in July, have drawn crowds from both parties as they seek to succeed the retired congressman. Republicans will likely hold on to the seat, which will help boost the House GOP’s razor-thin majority to barely give Speaker Mike Johnson (R-LA) some breathing room.
