CAIN: The word "settlement" versus the word "agreement," you know, I'm not sure what they called it.
KARL: Where have we heard talk like that?
CLINTON: It depends upon what the meaning of the word "is" is.
KARL: Even Cain's friends were troubled.
(UNKNOWN): How does Herman Cain end up parsing words in such a Clintonian legalistic way?
CAIN: Well, it wasn't intended to be Clintonian.
KARL: Next, the Cain campaign lashed out at Rick Perry, blaming him without evidence for spreading the story in the first place.
(UNKNOWN): Rick Perry needs to apologize to Herman Cain and, quite frankly, to America.
KARL: Not happening.
PERRY: No apology needed. We found out about this at the same time that I suppose the rest of America found out about it.
KARL: And throughout it all, Cain stayed in Washington, the jovial frontrunner getting more and more irritated by the day.
CAIN: Excuse me. Excuse me.
KARL: The lawyer for one of Cain's accusers says that she is standing behind her claims.
(UNKNOWN): Mr. Cain knows the specific incidents that were alleged.
KARL: A disastrous week, you think? Well, why, then, is he still statistically tied with Mitt Romney leading the pack?
There were other things happening this week, that Rick Perry speech in New Hampshire.
PERRY: Live free or die, victory or death. Bring it.
KARL: So animated, gestures so exaggerated, it became a YouTube sensation.
PERRY: I love Herman. Is he the best?
KARL: Finally, trending. Up, anonymous. Accusers and sources dominated the week's news, and the world still doesn't know their names.
Mark Block, down. Last week's Internet sensation has a rough week. He's even agreed to stop smoking, if Cain wins.
Mitt Romney, sideways. What else? Another top contender seems to go down, but Romney still doesn't go up.
Down, the NRA. No, not that NRA. The National Restaurant Association. Maybe too much hospitality?
CAIN: Excuse me.
KARL: Excuse me. With "This Week in Politics," I'm Jonathan Karl.
AMANPOUR: Thanks again to Jon Karl.
And President Obama was overseas this week at the G-20 summit. He comes home to a tidal wave of voter angst. Our new ABC News-Washington Post poll out today puts the president's job approval at just 44 percent. What's more, just 13 percent of Americans say they're better off than they were when he took office, and 74 percent say the country is on the wrong track.
The president is not the only one feeling the heat: 80 percent of Americans are frustrated with the federal government these days. Of that number, 31 percent are downright angry.
It's one reason perhaps that House Republicans are pushing back against accusations that they're do-nothing obstructionists. When I sat down with Speaker John Boehner, he brandished this flyer, showing the jobs legislation that he's passed. Of course, most of it was dead on arrival in the Senate. I asked the speaker how compromise has become such a dirty word on Capitol Hill.
AMANPOUR: Mr. Speaker, thank you very much for joining us.
BOEHNER: Good to be here.
AMANPOUR: Let's talk about jobs, obviously. You talk about trying to find common ground, but at the moment, there doesn't seem to be much. Even the infrastructure can't get through Congress. Where can you see common ground?
