Bill Clinton John Edwards, sex and morality

What bothered me most about the "Edwards affair" was the following comment Edwards made in 1999 abut Bill Clinton when his affair with intern Monica Lewinsky surfaced.
"I think this president has shown a remarkable disrespect for his office, for the moral dimensions of leadership, for his friends, for his wife, for his precious daughter," he said. "It is breathtaking to me the level to which that disrespect has risen.".
The morality of the statement is much worse than the problem of the affair itself.
