Are you saying Franken was not guilty of anything important enough to warrant his resignation? If so seems to me you are saying his abuse of women was not enough to warrant him going. If so then ok, that's your opinion.
Whether or not Jordan should have been treated the same has nothing to do with Franken's case, except for your suggestion that Gillibrand went after him to take him out as a possible presidential candidate in opposition to her. Whether you are right or wrong on that score i have no idea, still you have all the Dems who agreed with Gillibrand, and who didn't go after Jordan with the same purpose.
If Jordan is guilty of turning a blind eye at Ohio State then he should not be in Congress either.
