Why do you think there are Liberals who believe Clinton was never impeached...is it just plain ignorance?

It's the neocons who think that because he was not removed. They are so ignorant that they think it means he was not impeached. That's what you get for doing nothing but swilling beer bought with food stamps, spending all your time in tatoo parlors and vegetating in front of the TV in your double-wide watching NASCAR races and re-runs of the Biggest Loser.
