Governor Palin's endorsements were designed to do two specific things:
(1) Make sure the underdog conservative candidate's views were heard; creating healthy, competitive primaries
(2) Take out corrupt, establishment hack Republicans who would have continued business as usual.
Doesn't matter that Christine lost, or Miller may lose, because nobody but the diehard pundits and GOP beltway dreamers were thinking that the GOP would take control of the Senate anyway. But they served their purpose. RINOs like Castle, Bennett, Grayson, Lowden, and Tom Campbell in CA have all been eliminated in the primaries and cannot inflict further damage to the GOP brand. Murkowski, if she wins, will have greatly diminished power in the Senate. She will not have rank on committees and will be essentially a new-comer.
So for you to base Sarah's potential presidential powers on the fact that some of her candidates lost, is ludicrous. Because she has single-handedly revived the GOP and prevented the Tea Partiers from going 3rd party, and also more of her endorsements have won than lost.
The key thing, which The Hill Writer is overlooking, is that Sarah Palin made NO endorsement in the Nevada senate primary. Palin endorsed Angle only AFTER she won the primary.
