The intriguing nature of Fischer’s win is that the new GOP establishment, defined as the Club for Growth and Sen. Jim DeMint of South Carolina, had endorsed Stenberg. Palin endorsed long-shot Fischer.

If Stenberg had not gotten those endorsements, it is quite possible that most of his support would have gone to Bruning, who lost by 10,000 votes, and might well have pushed Bruning past Fisher into the lead.

But that didn’t happen, and the Club for Growth has been uncharacteristically quiet about its involvement…

If Palin picks her spots through the rest of this election cycle as well as she did in Nebraska, she might, without having spent a dime as a presidential candidate, be the second biggest name in Tampa this August, and her endorsement will really mean something down the home stretch this fall.

If so, Sarah Palin will indeed be back.
