It probably is best he resigned to ensure the seat remains in GOP hands. And of course he should have exercised better judgment knowing we live in a society that now looks on any adult-child interaction as predatory. I don't know what his intentions were. If he was looking to prey on this kid then f him and good riddance. But I'm not prepared to make that conclusion.
Since I posted what I did, new allegations were posted about his IMs. His intentions look pretty clear.
