Ah now comes the political party argument right? No, Rich was wanted in failure of over a dozen counts of filing and paying taxes, which if I am not mistaken is still considered a misdemeanor. Joe Arpaio was in clear violation of refusing a court order which resulted in the Criminal part of it being added. He, Arpaio and the Sheriff department was being investigated on many actions that violated the constitution and would be felony charges. You want to know what the real big difference is? It is called an Oath.
