He did not admit anything like that. He was very careful in his language not to dishonestly admit to things he doesn't believe. As he said in his statement, "Because all women deserve to be heard and their experiences taken seriously. I think that was the right thing to do. I also think it gave some people the false impression that I was admitting to doing things that in fact I haven't done."
Dozens of women who have known and worked for him, in some cases for decades, have certified that he treats all women with respect, creates a safe and supportive workplace and is a really good guy. I believe them.
Further, the allegations are seven random people out of thousands and thousands he has interacted with. The actions he is said to have taken are ones whose motivations can easily be misconstrued. (A kiss or a touch could be a rehearsal or an accident; masturbating in the office cannot.)
It is hard to imagine, if he's an abuser, why he only touched seven women out of many thousands at the MN State Fair.
We easily believe the women who accuse Trump and Roy Moore because they are well known scumbags. When Bill Cosby's accusers came out, everyone who had ever known him said, "No surprise. He was always a creep." Even Conyer, the people around him were unsurprised.
Al Franken? Everyone. Every single person felt like a punch in the gut. I don't know the name of an other Senator's wife but I've always known Franni.
Considering the testimony of the dozens of women who know him, the mildness and ambiguous nature of the acts of which he is accused, and the fact that these are women who barely intersected with his life, I do not believe for one second that Al Franken is guilty of being an abuser of women. I believe that the women who accuse him are either mistaken or badly motivated.
If there were a jury, I would never vote to convict him. I strongly believe that Al Franken is innocent and unjustly punished.
