You must have slept through his work with Teddy Kennedy in persuit of legalizing 20 million illegals.

Reagan actually accomplished amnesty for 20 million illegals and he is our hero. Bush's mistake was thinking that illegals and resident Latinos could become supporters of the Republican party like they did in Texas. That may be altruistic, but it's not worth all the vomitous screaming and blind hatred from conservatives.
