I agree, that at this point, he has done the right thing, though I would have liked things to turn out differently. Newt did the right thing and so did Bob Livingston.Trent Lott stepped down from his majority leader position, too.
On the other hand, the Dead-Conscience Democrats* rarely step down.
*The Democrats are so corrupt that their consciences are dead.
To quote the Gipper: There you go again.
If moral equivalence arguments are bad when the other side does it, it even worse when we do it after railing against it for so long.
Lott, Packwood, Livingston, Gingrich, et. al., did the right thing not because the "other side" was so vicious and unrelenting, but despite them.
Right and wrong should have no political affiliation.
