Lets quote the ever popular Chris Rock:

Clinton damn near got impeached ... and for what? Lying about a blow job so his wife wouldn't find out. Everyone acting like he's this all holy person. He aint Reverend Clinton. He aint Pastor Clinton. He aint Maharaja Clinton. He's just Bill Clinton. He's just the President. He's just a man. A man is basically as faithful as his options. So he bought her some gifts ... so what?! You cant buy your friend a gift?! So what if he got her a job, half the people in here got their job because a friend recommended them. Hell, she was blowing him for 6 months, the least he could do was give a letter of recomendation. Now you see all these fat republicans 'I would never do such a thing ...' ... well no one is tryin to blow you! Aint know one tryin to give Newt Gingrinch some. It's all Hillarys fault. Thats right, I said it. It had to be said. Shes the first lady, she's supposed to be the first one on her knees to suck his dick. Because women ... you know your man. You know your man better than he know himself.

Besides ... what does a man who cheats on his wife have anything to do with running a country? What consenting adults do behind closed doors is their business, not the publics. That's why it's behind closed doors.
