Michael: of course, you make an important point.
It is human nature, though, to laugh when the self-professedly virtuous prove their flaws.
The problem, Michael, is that this gambling is a long term pattern of behavior, not a single example of a "mistake." His apologists' arguments are not very convincing, either. Fellatio is not against the law, either, but even the biggest Clinton apologist (which I am not) would deny that the man was morally bankrupt.
And, when a man makes his career of being a moral scold, and that scolding is based on traditional "Christian" values, then the glass house/beam in your own eye factor comes into play. I feel little sympathy. (One could also question the morality of our entire revolving door substructure of "lobbying" and influence peddling-the source of a good deal of his income, but that's another issue entirely, and not by any means a purely Republican one)
