Why?
Everybody's for it.
Just for the record:
Not the Democratic Party and Dick Gephardt (who promised amnesty to all illegals who vote and support the Dems in the 2002 elections).
............and also (I'm afraid to say) linguine-spined Republicans who are afraid (and rightly so) they will be labelled as racist by the Dems and every other special interest group from the Agricultural Lobby, to La Raza, to the idiots in the mainstream press.
