We know, from Franken's own stories, that he spent enough time with "rowdy" crowds: SNL and, as posted here, USO tours.
So I wonder, I don't know, whether in some of these circles when people would meet they would not just shake hands, or air kiss, or even peck on the cheek, but would grab each other butts. After all, we've seen images of the Tweedy lady grabbing asses of co-performers on USO tours.
Thus, it is probable, I think, that Franken was used to greet friends and fans this way and automatically did it again, not thinking.
And he really did not know how to answer Esme Murphy when she asked him whether he'd ever grabbed asses.
He will just have to be more careful and conscientious when he meet people - men and women. Yes, will not be spontaneous, perhaps skip the hugs, too.
And let the chips fall where they will.
What I did not like was tpt Cathy Wurzer's suggestion that he steps down and for Dayton to appoint a woman. If he does step down - which, at this point, I don't think he should - Dayton should appoint a qualified, trusted Democrat. Enough with the "identity" politics. In my opinion, it has caused more damage than good.
