GW Bush and his lying liars!?

Ok, president/s have been impeached for numerous of stupid reasons, right?! Ok, Bush and his lying liars are not impeached? What the hell is up with that! He lies and starts a war that really should have never been started! And then him and his lying liars lie about whats going on in the war, and they don't get impeached! I personally think that whoever voted him in as president for another 4 years, is DUMB! Ok, so why didn't we impeach him and his lying liars a long time ago?
