Which one of the synonyms will Rudy use to describe his flip-flop on the War On Immigrants? In 1996, Rudy said:

The anti-immigration issue that’s now sweeping the country in my view is no different than the movements that swept the country in the past. You look back at the Chinese Exclusionary Act, or the Know-Nothing movement — these were movements that encouraged Americans to fear foreigners, to fear something that is different, and to stop immigration.

Rudy today:

If they want to become citizens, they should have to “get on the back of the line,” he said. “And then, at the end of the line, if they are ever going to become citizens,” he said, “the thing I am really interested in, they have to read English, write English, speak English and be able to understand the basics of American civics.”

But, like abortion, this is not the first Rudy flip-flop on immigration policy:

When he worked in the Justice Department under President Ronald Reagan, he defended the administration’s policy of keeping thousands of Haitian refugees in detention centers and denying them asylum. When he first ran for mayor in 1989, with immigration a potent subject in city politics, Mr. Giuliani moved quickly to distance himself from that policy, and embraced a role as both a spokesman and protector of new immigrants through his power as mayor.

There is not a position he won't abandon or a principle he won't sacrifice to win political office. There is no doubt that if Giuliani was running for Senate in New York this year he would hold the exact opposite views he now espouses. Is there a less principled person in politics than Rudy? Joe Lieberman? It's close.
