Below are some of the notable comments made by the Powerhouse Roundtable Sunday on "This Week with George Stephanopoulos." Roundtable guests included ABC News political analyst Matthew Dowd, TIME Magazine's Joe Klein, Washington Post columnist Ruth Marcus, Wall Street Journal columnist Peggy Noonan, and The New York Times' David Sanger, author of "Confront and Conceal."

POWERHOUSE ROUNDTABLE

1. Dowd identifies the 'one good thing' about Grover Norquist DOWD: Both sides of the aisle…know Grover Norquist is an impediment to good governing and not - the only good thing about Grover Norquist is he's named after a character from "Sesame Street."

2. Klein says Boehner may need to 'risk his speakership in order to have a legacy' KLEIN: I think that there is a centrist coalition to pass this in the House. You know, you may lose the Tea Party on the right, you may lose some of the more extreme liberals on the left, if you do entitlement reform. But I think you've got 250 votes for something in the middle. It depends on whether John Boehner is willing to risk his speakership in order to have a legacy.

3. Klein calls cease-fire a 'defeat for everybody' KLEIN: Everybody's claiming victory. I think it was a defeat for everybody.

4. Sanger says success of Iron Dome sent a message to Iran SANGER: That was a message to the Iranians, that if they thought that they would manage to get these missiles into the Gaza or into Lebanon in a sort of stealth Cuban missile crisis kind of scene, where you slip in the missiles, that, in fact, they would be significantly less effective….The Iranians also learned a few lessons from this. They learned what the Israeli capability was.

5. Dowd says Israelis and Palestinians 'don't have a meaning' without a conflict DOWD: I don't think either side can see a future where conflict doesn't exist, because the conflict has now given their lives meaning, and if they take away the conflict, they no longer - the Israelis don't have a meaning and the Palestinians don't have a meaning.

6. Noonan calls election 'rebuffing' of Republicans NOONAN: From the beginning, it struck me as this is not just the re-election of a president. This is the rebuffing, if that's the right word, of the Republicans.

7. Dowd warns of Republican failure in 2016 election if lessons aren't learned from 2012 DOWD: Yeah, and I think if the Republicans take away the wrong lessons from this, they're going to repeat this and fail again in the next presidential election

8. Marcus tells Democrats 'demography isn't destiny.' Marcus: I think there's also a danger for Democrats here in resting on their laurels and taking the lesson that demography is destiny. Demography is not destiny….The Republican Party…is just as capable of changing and modernizing itself for the times as the Democratic Party was in the aftermath of McGovern and Dukakis. We got Bill Clinton.
