Honestly, he probably thought he had it in the bag, that there was no way Jeff Sessions' seat would ever get replaced by a Democrat.
I'll be many of the 650,000 Trump voters who stayed home thought the same thing; they could keep their hands clean and Moore would still win.
The biggest lesson we need to take away is this: If properly funded and motivated, the Left has the capability to rally the troops, have volunteers canvassing the neighborhoods, manning the phone banks, and getting Democratic voters to the polling booths.
There is no Republican seat so safe as to give us the luxury of running fringe nutjob candidates and then staying home on election day.
The second best option is to indeed rally up jaded traditional GOP support. GOP is the glass half full in optimist speak.

America isn’t in a good enough place yet to benefit from a Roy in the Senate except as a GOP placeholder. But understanding well-meaning but premature evangelical fire as I personally do, I’d urge Roy to take heart that he did as well as he did, and to retreat into humble company with Christ to later go on a better and more effective mission. You tried with what you knew. If you want to see anything close to the famous Ten being honored, support the evangelists, Roy.
