Mr. Oppelt's dismissive attitude towards his own misdeeds is quite concerning. He seems unwilling to simply take accountability or at least acknowledge that he made poor choices. Mr. Oppelt makes a lot of excuses, but never humbles himself to own up to his actions and apologize to the community for which he wishes to serve. 
Mr. Oppelt appears to lack self awareness, and his pattern of irresponsible behavior speaks to his character. Additionally, if you are a candidate for public office it is not "petty to be talking about this stuff," as Oppelt claims. The public has the right to make informed decisions. You do not get to edit your life of your misdeeds and tell the public what is relevant about yourself and what is not. Perhaps Mr. Oppelt doesn't think arbitrarily breaking the law is a big deal, but many in the community do.
It really makes me wonder-- if these are the discoverable, documented misdeeds of Mr. Oppelt, what else has he done?
