"Back in late 2017, it looked like Franken was going to weather the charges of inappropriate conduct against him, until Democrats apparently decided to sacrifice him..."

"... presumably in part to demonstrate that they could police their own.... The coup was quick and brutal. First, Senator Kirsten Gillibrand posted on Facebook a call for him to resign. Then, in quick succession, 13 more Democratic women senators (and a majority of the entire caucus) joined her. Whether Franken was guilty or innocent -- and he'd asked for a hearing -- his position became untenable. The day after Gillibrand’s shiv, he announced his intention to resign. (Chuck Schumer had told him to be out by 5 P.M.) If it looked like an orchestrated takeout, that's because it probably was. Biden -- even if innocent -- is now in a position where he must constantly worry about getting Frankened. By whom? Well, by the same sorts of powerful Democrats who helped him win the nomination (perhaps by helping orchestrate the well-timed withdrawals of Amy Klobuchar and Pete Buttigieg).... I'm also not saying 'they' want to replace Biden now.... But they could change their mind, and quickly, if he gives enough of them enough reason -- either by faltering, or pissing them off, or a combination of the two.... Biden probably wasn’t about to forge bold new directions.... But now Biden’s really in no position to step on anyone’s toes. Power has shifted away from the candidate."

From "The Frankening" by Mickey Kaus.

That could be read to say that Biden's position is stronger than ever. The Party wanted Biden because he would do what they want, and now there's even more reason for them to believe he will. He's boxed in.
