I have no problem with him being disloyal to his marriage. That's between he and his family.
My problems with the incident are:
1. His judgment in using Craigslist classified ads as a dating service.
2. His judgment in not using a suitable pseudonym to better disguise his identity.
3. His judgment (if he did use a pseudonym) in sending an easily identifiable photo of himself, a public figure, to an anonymous person on Craigslist.
4. His judgment in using his real name, identifying himself as a divorced lobbyist and then sending a photo of himself to the woman after having his two-term election material and photos plastered all over the internet.
5. His judgment in doing all this after having written an op-ed in 2009 warning teens of the dangers of the internet in which the first two paragraphs of it read:
Through the Internet, with a few keystrokes and the click of a button, a young person can call up information for a research project, make new friends or discover new hobbies.
At the same time, responding to what may seem like a friendly e-mail or an appealing marketing offer can have serious consequences. Private information and images can so easily be transmitted to friends and strangers alike.
It is a case of career suicide by internet email.
