As a Democrat, I neither want Harris (R), nor McCready (D) nor the defeated primary-Republican to be seated. I want NC-09 to remain vacant and a new special primary and general election to be held, which determines a winner.
And I want a tough prison sentence for the Republican guys who collected absentee ballots on their own and destroyed some of them, a hefty financial penalty of several millions to the state GOP, which is paid to the state to reform the state election system and a law that prevents such election fraud in the future.
This is the most reasonable outcome, but I would say a special election should be called as soon as possible - ideally, with the costs being billed to the guilty parties who sabotaged the election after a civil suit.
