In the worst scenario if all is true, Roy Moore allegedly kissed a 14 year old girl about 38 years ago when he was in his 30's. Allegedly kissed one girl, maybe flirted with a few other girls. No allegations of actual sex. And the context of that is impossible to establish, and highly suspect to have surfaced this late in the election, especially after Roy Moore has already held so many political positions, for decades.
Both Elvis and Jerry Lee Lewis married girls that age and had long careers after. It was a different time. Worst case scenario. And more likely, it's just a smear job by the Democrats and DNC/PR-wing media. And this allegation doesn't even say that he had sex with the 14 year old girl back then. If the same were said about any Democrat, the media would give it a complete free pass.
