From the Chicago Tribune interview with Barack Obama, December 9, 2008:

Asked if he would support the extension of the fence between the U.S. and Mexican border, Obama deferred to his nominee for the Homeland Security Department, Janet Napolitano.

That's leadership for you.

From the Los Angeles Times, November 23, 2008:

Napolitano has not been a backer of the border fence currently under construction: "You show me a 50-foot wall, and I'll show you a 51-foot ladder," she has said.

Of course, the Other One wouldn't have built the fence, either. Cold comfort.
