Right, see I think we've already had enough criminals and whackos in Congress, and I don't want more. You seem to think that the way to improve the situation is to elect Ann "So Freakin' Cracked That She Enrages This Apathetic Country In Which Half Of The Adults Can't Be Bothered To Vote, But More Than Half Have An Opinion On This B!tch Strong Enough To Make Them Froth At The Mouth" Coulter.
See, I can think up funny nicknames, too.
Congress needs to be diverse in their opinions, which would be a mark in Coulter's favor; but they also need to be independent, willing to follow their own opinions rather than join the crowd. Coulter is influential enough that she would skew opinions away from where they should be, as people lined up to follow her, or to oppose her, rather than doing what they personally think is right. She would be a polarizing force, rather than a unifying one, and that would not be helpful.
