Just posing the question - If Hickenlooper didn't run in 2006, when the larger environment in Colorado was a definite positive, why would he run in 2010, when the larger environment is, at best, probably going to be somewhat negative?
Not that this necessarily means anything, of course.
Wasn't Ritter handpicked by the Dems as the safest, most electable candidate, given his conservative stances on abortion and labor? Hickenlooper may not have gotten any institutional support, or maybe he just didn't want to run in a tough primary.
