GINGRICH: I do not believe that the people of the United States are going to take people who have been here a quarter of a century, who have children and grandchildren, who are members of the community, and expel them.
KARL: That's a tough sell in a primary where electric border fences and alligator-filled moats can be applause lines. Gingrich argued it's about family values, not amnesty.
GINGRICH: I'm prepared to take the heat for saying let's be humane in enforcing the law, without giving them citizenship.
KARL: Romney chided Gingrich for going soft on illegals.
ROMNEY: When we have had in the past programs that have said that the people who come here illegally are going to get to stay illegally for the rest of their life, that's going to only encourage more people to come here illegally.
KARL: Tough talk. But can Romney really attack Gingrich on this? Look at what he said just four years ago.
ROMNEY: The 12 million or so that are here illegally should be able to sign up for permanent residency or citizenship.
KARL: Romney unveiled his first TV ad this week, and it was a doozy, twisting and misrepresenting President Obama's words.
OBAMA: If we keep talking about the economy, we're going to lose.
KARL: But Obama was talking about John McCain, not himself. Here's what he actually said.
OBAMA: Sen. McCain's campaign actually said, and I quote, "If we keep talking about the economic crisis, we are going to lose."
KARL: The Obama campaign cried foul. Romney made no apology.
ROMNEY: What's sauce for the goose is now sauce for the gander.
KARL: Trending this week, down, Congress. The supercommittee's failure was inexcusable and embarrassing. And check out how congressman Don Young treated historian Douglas Brinkley before his committee.
REP. DON YOUNG, R-ALASKA: And the I call it garbage, Dr. Rice, that comes from the mouth--
DOUGLAS BRINKLEY, HISTORIAN: Dr. Brinkley. Rice is a university.
YOUNG: No, OK--
YOUNG: -- anything I want while you sit in that chair. You keep quiet.
BRINKLEY: You don't own me. I pay your salary.
KARL: Down, Herman Cain. What's worse than controversy? Irrelevance. The only time he broke through during the CNN debate was when he mangled Wolf Blitzer's name.
HERMAN CAIN, PRESIDENTIAL CANDIDATE: No Blitz, that's oversimplifying it. I'm sorry, Blitz, I meant Wolf, OK?
KARL: Up, Liberty the turkey. He gets a presidential pardon and a job offer from Wild Turkey.
Jimmy Fallon, down. He invites Michele Bachmann on his show, and then his band plays the song "Lyin' bleep-bleep" when she walks out on the stage. Not funny.
For this week in politics, I'm Jonathan Karl. Christiane?
AMANPOUR: Thanks, Jon. And of course, Jon will join us on the roundtable in a bit.
Of course, the week's big story was the total collapse of the supercommittee. Washington is now once again in crisis mode, facing yet another ticking clock. It's enough to leave even the most upbeat Americans thoroughly vexed. And joining me to discuss the way forward, former supercommittee member, Pat Toomey, Republican of Pennsylvania.
Senator, thank you very much for joining us.
TOOMEY: Good morning. Thanks for having me.
