Akin can still get off the ballot, but he can’t be replaced — assume all of you naysayers would rather McCaskill run unopposed?

You are mistaken. Akin can absolutely be replaced, but it has to happen quickly. Either Brunner or Steelman can replace under MO election law if the candidate withdraws; there are no "sore loser" prohibitions.

Then who should replace him on the ballot????
