Rush Limbaugh, who has always been very cautious on immigration, has

finally come out of the closet as an immigration critic. On his show

Friday, He went on at length about the threat that the president’s

misbegotten amnesty/guestworker plan poses to the Republican Party (echoing

David Frum’s NRODT cover piece), and even criticized the wage effects of

massive low-skilled immigration. Rush is the latest example of what John

Fonte calls “second-thoughts conservatives,” who have freed themselves from

the libertarian dogma on immigration.
