I will take that scenario in ANY election.
Yes the district will stay red. Jake Ellzey is a decorated veteran and war hero. Graduated from the Naval Academy. Trump endorsed Susan because they feared the seat might go to the RATs because of the GOP splitting the vote. According to a very early poll, she had the highest name recognition and had the best chance against the Dem. Since it didn’t turnout with D vs R, Trump should not get involved further. His endorsement could have made the D be the second highest vote getter instead of Ellzey who won the early vote.
