Arpaio is dead to me since he decided to be a spoiler in the Republican primary in last years Arizona Senate race.
IMHO, Joe did a lot of good over the years in AZ.
However, he failed to recognize when it was time to hang up the badge and retire. Had he done so, he could have gone out in style and in a way that would have ensured that his replacement would be a conservative likely to continue to pursue the same or similar conservative policies, even if approached in different ways.
That was a big failure... but I still love and appreciate the guy, his courage, brashness, outsized ego and all.
