It certainly does matter. Only an idiot loses without trying to understand why they lost.
The Republican Party by suspending Moore's funds, made it appear that he was guilty. That appearance of guilt abetted by their stupid and immoral haste to condemn him on the basis of unprovable accusations, easily cost 25,000 votes, which was the margin needed for victory.
Why did George Herbert Walker Bush lose to Bill Clinton in 1992?
He lost because he lied when he said "Read my lips, no new taxes!"
This breaking of his word caused a major schism in the party which created a demand for someone like H Ross Perot. It also took away from George HW Bush the "character" issue, so he could not longer accuse Bill Clinton of being a big bag of lying sh*t, because the minute he did so, the media weapon would be out with that video of "READ MY LIPS! NO NEW TAXES!
Thereby reminding voters that George HW Bush lied to them.
So yeah, sensible people try to understand why we lose an election. They do not just stop at "We Lost!"

Bush lost to Clinton because of Perot. Perot got 20% of the national vote.
