Rudy Giuliani doesn't sound like he likes local and state governments making provisions to enforce immigration laws--and doesn't sound too keen on workplace enforcement, either (e.a.):

WASHINGTON - Responsibility for stopping illegal immigration belongs to the federal government and not to cities, states or businesses, Republican presidential candidate Rudy Giuliani said Tuesday.

Giuliani told small-business owners he would not punish them for unwittingly hiring illegal immigrants.

Federal officials are "trying to put the responsibility for this on employers, on city government, on state government," the former New York mayor said during a conference call arranged by the National Federation of Independent Businesses.

"The simple fact is, nobody but the federal government can stop people from coming into this country illegally, and the federal government does a very bad job of that," Giuliani said.

He said no other presidential candidate will solve the problem.

"If you elect a Democrat, they're just going to open the borders, and more illegals are going to come in," he said.

"And if you elect one of my (Republican) opponents, they want to crack down on cities and states, and they want to crack down on businesses, but they don't want to solve the problem," he said. "If I become president, in a very short while, you will not be able to walk into the United States without identifying yourselves."

Giuliani says he would build a fence along the U.S.-Mexico border that includes high-tech monitoring to detect those trying to enter the U.S. illegally. He also calls for hiring more border patrol agents.

Legal immigrants should be issued a tamper-proof, federal identification card, he said, "and if something is wrong with that card, it's the federal government's responsibility, not yours."

He seems to be emphasizing border enforcement above all.
