Michael Sandoval asks an excellent question: Why didn’t Sarah Palin make an endorsement in the Colorado Republican Senate primary? And I suspect he’s onto the answer: It may have been a no-win mess for her. McCain was campaigning for Norton. Buck seemed to have the tea-party love, though he did not seem all that comfortable with it. And in confusing races, Palin’s Facebook nod does not necessarily work magic. Todd Tiahrt stands as evidence of that.

Someone who did take a risk and take sides there was former Pennsylvania senator Rick Santorum, who has been spending a lot of time in the likes of Iowa recently. Well, he spent a Friday recently in Colorado, campaigning for Norton.
