Quite a dangerous precedent is being set here.
If mere allegation is enough to call for resignation, yes, and you can bet your bottom dollar that that axe will be used against the GOP at every opportunity, but even more to trim the Congressional Ranks of anyone who won't play nice with the Uniparty.
This will permit the consolidation of power into the hands of the Capitol Hill Mob, and the people will lose any say in what happens up there. This is the reason for the attacks on Moore, who would be the worst nightmare for McConnell and Co. on the Hill.
