Gov Romney has released a radio ad critical of illegal immigration -- attacking "sanctuary cities" where illegals find jobs and little local efforts to send them home.
"Sanctuary cities become magnets that encourage illegal immigration and undermine secure borders." -- announcer, Mitt Romney radio ad
As mayor of New York City, Mr Giuliani inherited a city policy from his predecessors under which city employees did not notify federal authorities of an immigrant's legal status. Mr Giuliani never changed the policy.
The ad strikes on radio -- as videos of Mr Giuliani praising immigrants while he was mayore are getting lots of hits on sites like YouTube.
