I think Rush is for open borders and illegal immigration. He never wanted border issues brought up on his show, he never brought out the facts about the problems even when Republicans started saying they wanted to secure the border, deal with illegals already here. He has said several times that there is no way to deport illegals.
He supported Governor Jan Brewer during th SB1070 fight with Obama.
It is time to regulary call him NAFTA Rush. This is the central issue of the General election in battleground states, and Rush’s embrace of NAFTA has been a lot more devastating to the country than Trump complimenting the Clintons.
