That is a "fact" not in evidence. The rank and file may trust Moore, but they also know the effects of a massive apparatus for spreading lies, and the occurrence of backstabbing on the part of the Republican party.
In fact, if these same people trusted Roy Moore, he'd be doing better than 10% in the GOP primary polls.
That is also just speculation. They may trust him, but again they are aware of the power of the forces arrayed against him. They also understand that someone else can give them what they want without having to go through all that crap thrown at Moore.
Face it, dude -- the guy's a loser, and his inane lawsuits and public temper tantrums have gotten too tiresome and predictable even for a lot of people who supported him in the past.
He isn't a loser, he is a victim of backstabbing and lying by the national media apparatus, and the people doing the backstabbing and the people doing the lying on the national mass communications systems are our real enemy.
