Al Franken is expected to make an announcement Thursday.
Donald Trump is accused of far worse. He should also resign.
And Roy Moore should step down, accused of sexual assault, attempted rape, and child molestation.
There's no question that what Trump and Roy Moore have done is far worse than what Franken did.
However, now that Franken has 7 accusers (2 weeks ago it was only 2) and lots of Democratic senators are calling on him to resign, he has to go. If he stays he'll be an ineffective pariah and the Republicans will bellow that he's the reincarnation of Jack the Ripper.
If he resigns, Democratic governor Mark Dayton will appoint a Democratic replacement. The Republicans will gain nothing except not having to listen to Franken's sarcasm & satire.
