Risch. Otter says he hasn't committed anyway, but I doubt that's true.
If not Risch, Simpson is most likely, and then one of the lower statewide office holders. I'd imagine Otter's list probably looks something like this:
1-Risch
2-Simpson
3-Some downballot office holders/legislature leaders
4-Every other single registered Republican in the state who is not Bill Sali
5-Bill Sali
Sali :fingers crossed: America comedians need one the four bat-sh*t crazy House Republicans (Marilyn Musgrave, Jean Schmidt, Barbara Cubin, Bill Sali) to ascend to the World's Most Exclusive Club. Colbert, Stewart, time to get on your knees and pray to the political gods.
