The only way to keep the general populace from getting trampled as far as they will allow is to push back against all this.
I've said elsewhere, vote out every incumbent Congressperson. Once the current paid members are gone, if the new set appears to be voting by donor status, vote them out too.
Keep voting them out until we find a few decent souls who realize that we the people are serious about being represented, not sold.
I would use campaign contribution reports as a "who should be first out the door" list... individual personal donations of fixed maximum size only, everything else counts against.
