I posted about this possibilty the day Gale Norton resigned, and now here we are.
Risch isn't the incumbent until Kempthorne resigns, which he probably won't do until he's confirmed, which could take a little bit of time.
But tomorrow is the filing day, and Jim Risch tonight is making the most momentous decision of his political career - does he stay with his Lt. Gov. slot since he said he wouldn't run for Governor, or does he become a last minute entrant into a primary that Butch has all but locked up.
If he stays running for the Lt. Gov. spot he'll be the shortest term Governor in history and probably remain a political player assuming he wins this fall (likely). If he decides to run for Gov, and loses the primary, he's done with both jobs next January.
But if he does switch his filing, run for Governor, and throws, say, a million bucks into advertising between now and the May primary, hide your kids because it will be the wildest political scenario I've ever seen, and potentially a really bloody primary.
This is really, really fascinating.
