Via Colorado Pols, this story, if true (the sourcing is spotty), is quite interesting. For those of you not following Colorado's gubernatorial race, Scott McInnis, the likely GOP nominee, has been damaged by a scandal. Basically, it turns out he got paid $300K to write a bunch of water policy articles a few years ago, had some water policy expert write them for him, and then passed off the work as his own. When caught, he tried to blame the policy expert, who wouldn't play ball. Anyway, even thought this hasn't hurt him in the polls much yet, state Republicans are concerned this will really hurt him in the general election, which is already looking like a tight race.
However, they're not asking McInnis to bow out yet, because they want him to beat Dan Maes in the August 10th primary, since Maes is a Tea Partier type who would almost definitely lose in the general. So they're basically waiting for McInnis to beat Maes and then they're going to try to talk McInnis into dropping out. I'm not sure whom they'd replace him with. Possibly State Sen. Josh Penry, who was pushed out of the race last winter.
Anyway, it's an interesting case of party insiders thwarting primary voters, making estimations of future public opinion, etc.
