Respectively, here and here.

As background to the grumbling link - It appears GOP bosses and true believers differ on guv choices, this link. Best guess is the bosses have it in the bag, grumbling will continue but will lessen over time leading to the general election, and Joe Repya did move to the IP for a reason.
Not that other true believers will follow. But they may.
And the GOP has Horner moving to the IP, for a spell at least, for reasons the bosses might know.
Siefert, Emmer - I'd fear both. Siefert is a Pawlenty clone, mediocre to the core. Emmer would be mediocre with more right-wing leaning. Either way an unwholesome-to-thought-and-progress-and-enlightenment choice. How do they find those people? And Quist. Maybe it's trace chemicals in the drinking water.
