Republican Arpaio endorsed Napolitano for governor instead of her Republican opponent, Matt Salmon. His endorsement effectively handed the governorship to Napolitano.
It was quite obvious that Arpaio, who famously holds grudges, had endorsed her as a bit of petty payback to Arizona Republicans for not picking him to be the gubernatorial nominee.
Yes, I remember that now. Talking of holding grudges, someone I know quite, quite well is in the journalism business here in Arizona. For a decade or more he has been one of the few reporters that Arpaio would talk with. Recently, this person began to ask Joe where the money was coming from to pay for the county sherrif officers who accompany him as a bodyguard on his personal book-signing tours. Needless to say, this friend is now in the dog house with Arpaio and probably will be there forever.
