Exactly my point. Republicans are going just as soft on Franken as they did on Trump and Democrats are also going soft on Franken when they didn't go soft on Trump. Ergo, he's getting a pass for being a Democrat. I'm not sure what's so confusing about this.
Ok, but I don't think it's because he's a Democrat, 538 speculated that probably the vast majority of men in Congress, regardless of party, have a history of this kind of thing and when the Franken allegations came out everyone was worried that they'd be next, so no one wanted to come out swinging calling for his head.
