But it's more an up-versus-down issue because the research has shown that opinion leaders, whether they're elected officials, journalists, business leaders - it's academics, religious leaders - they have dramatically different views on immigration. A

Well, nobody's being deported - nobody - practically. And so what the people down there getting is the American government is telling us that you're not going to be able to stay.

Of 472 civilian occupations defined by the Department of Commerce, only six are majority immigrant (legal and illegal). These six occupations account for 1 percent of the total U.S. workforce. Many jobs often thought to be overwhelmingly done by immigrants are in fact majority native-born: 51 percent of maids are U.S.-born, as are 63 percent of butchers and meat processors, and 73 percent of janitors.

Well, enforcement theater is OK if it's reality theater. In other words, obviously, you want to make it clear, you want to make people see that the law is being enforced.
