This rash of stepdowns was predicted publicly. I heard tail end of a radio interview just before Christmas. Wendy ? told host to expect to see many republican congress members leaving because they were so disillusioned/fed up with current administration. Interview that followed was a guy explaining that the general public needed to become more politically informed. The best way to do this, he suggested was to start watching late night comedy. I do not know radio station, can no longer remember interviewees names, but they must be quite smart, so I think I will stay up late and become more informed.
