A very troubling email going around from Sheriff Joe Arpaio of Maricopa County, Arizona. We can debate whether or not such an email should properly be called an effort at vote suppression, but I hope that there is broad consensus that the chief law enforcement officer of a county should not be injecting himself in such a politicized way in election administration issues. The sheriff’s job is to ensure that voters can cast votes at the polls free of intimidation and violence. It is not to inflame passions based upon unsupported allegations of massive non-citizen voting (enough apparently to swing an election). Very sad.
