Dont think he hasnt thought of it.
As much as I dislike the guy personally I have and will continue to vote for him. He is a narcissistic self centered individual, but that seems to be just what is required for that office, cause he does it really well.
My favorite Sherrif Joe story was a few years ago, there was some college eco terrorist driving a gray Honda that was going from Idaho to Washington and maybe northern Utah, blowing up mailboxes and making a political statement about some crap. The manhunt was on, every news network was running the updates and breathlessly reporting about the danger we all were in. Well at that same time somebody left a big metal spider-looking creature in Sheriff Joe's front yard. He immediately called the bomb squad in, then called a press conference and tried to say it was the same guy. Like the kid just decided to make a detour from Idaho to Fountain Hills, Az just so he could drop a metal toy in Joe's lap. Trying to tap in to the national coverage this guy was getting cause his spotlight just isnt big enough.
