Pete Wilson just gave an interview addressing Prop 187. His opinion is that it would pass by even a bigger majority if it was put to a vote again. And he said this before Davis signed the Drivers License bill.
Hugh is against 187 because the national party has decided to pander to hispanics. They think they will achieve that by doing nothing to stop illegal immigration from Mexico. Hugh is a party hack first and foremost, because he wants power and influence within the GOP. He will have no power and influence if he isn't a good boy always following the party line.
The social problems of mass illegal immigration don't affect yuppie Irvine. He didn't grow up here, he hasn't got family living in neighborhoods wrecked by the policies he embraces. When the interests of California conflict with Hugh Hewitt's desire for political power, the interests of California lose.
