The pre-emptive Republican criticism of Roy Moore's candidacy is coming from establishment/RINO Republicans like John McCain who never supported Trump or pro-Trump candidates like Moore in the first place.

I still don't see any actual evidence against Roy Moore that he actually flirted with/hit on/forced himself on any 13 or 14 year old girls. Just the ALLLEGATION unleashed that he did so 38 or 40 years ago.
An allegation conveniently unleashed right before an election, at a point strategically selected by smearmeisters where no Republican could selected as a replacement candidate. Roy Moore has roughly 50 years of life in various public appointed/elected positions, and NOW these allegations are suddenly unleashed?!
That is just TOO convenient for Democrats, for his establishment Republican opposition, and for the Orwellian Newspeak DNC-partisan media.
