The three obvious replacements discussed on radio have been Wagner, Emerson, and Hartzler — all Congresswomen who have safe districts and easy wins ahead of them. Which of them would be foolish enough to risk a certain and easy election for a fight with a seasoned pro for which the outcome is uncertain??? Would you???
The two obvious replacements that you did not mention, Sarah Steelman and John Brunner, were each projected to beat McCaskill in pre-primary polling. Why not choose one of them? They could easily put campaigns back together and would actually have a chance to win.
