It seems like it's mainly the democrats that keep bringing up this crap, and I guess the reason is to take away the memories of one Bill Clinton and his escapades before and after his stint in the White House.
One thing that should be noted in all of this, although the whole thing stinks, almost without exception, when a Republican is caught, he resigns his position rather than cause pain and expense to the public and family, but, when a democrat is caught, you cannot get them out without much kicking and screaming how they did nothing wrong.
