It would not surprise me if Jeff is doing this so Joe can run against Flake. That would mean least 3 in the Primary which is what the GOPe wants. The only way l see Flake surviving is if the base is split.
Let Joe Arpaio organize the Federal prison that will house the criminal element from the Democrat Party: Obama, Clinton, Holder, Jeh Johnson, Susan Rice, etc.
I suggest locating the facility down by the Yuma Bombing Range near Ajo.
The prison industry could be collecting trash dumped by aliens. The other task could be planting cactus....this group has experience handling prickly objects.
