I had a feeling this would happen. Conservatives felt Kavanaugh was a "witch hunt", so they'll probably feel that way about every accusation now. I remember feeling at the time that Moore probably won have won if the election had been held in December 2018 instead of December 2017.
The AL Senate Special happened on the day where Trump's approvals were at the lowest point of his entire presidency: if the midterms had been held on that day, the Dems probably would have taken the Senate and gained 60+ seats in the House. Of course, the fact his approvals had sunk so low probably had something to do with the fact that people were constantly hearing about Roy Moore.
