Because he could. Silly question from the unwashed masses.
Exactly right. Bill Clinton has so lowered the bar that any Democrat politician believes that he/she has carte blanche to partake in all kinds of sexual behavior and be given a pass by the voters.
As long as you share Democrat voters political views and are a charismatic politician, you can be a complete scumbag in your private life.
Your reap what you sow and Democrats who gave Clinton a pass and condemn Weiner are utter hypocrites.
