We simply have a hard-core set of voters - citizens who vote in every election - that will vote straight R no matter what. Even experienced law enforcement professionals who campaigned and/or ran against him, laying out the facts of what was really happening, didn't seem to sway these voters. I sincerely wish those who blindly kept voting for Arpaio would now shoulder the burden of paying the $20 Million in costs for his trial and judicial settlements and let those of us who never voted for him keep that tax money.
To me the moral of this debacle is that a sheriff of a county of 4.2 million people needs to be an appointed position, not an elected one.
