Sunday Sound: Heard on "This Week" Below are some of the notable comments made Sunday on "This Week with George Stephanopoulos." Guests included White House senior adviser David Plouffe, Romney campaign senior adviser Ed Gillespie, ABC News" George Will, Cokie Roberts, Donna Brazile, Matthew Dowd, and Ronald Brownstein of the National Journal. Plouffe thinks Karl Rove will confront "crossroads" after Tuesday's election PLOUFFE: I think Karl Rove might have said that because a few days ago he predicted a big Romney win, and my sense is Karl is going to be at crossroads himself on Tuesday when he tries to explain to the people who wrote him hundreds of millions of dollars why they fell up short. Plouffe views the Romney campaign's ads and visit to PA as a "desperate ploy" PLOUFFE: This is a desperate ploy at the end of a campaign...the truth is, they're throwing some ads up and Governor Romney is traveling in the state he's not going to win. Gillespie claims Obama is in "deep trouble" based on the polls GILLESPIE: When I look at the data, when I look at where the president is, when you're the incumbent president of the United States and you are at 47 percent or 48 percent on your ballot two days before the election, you are in deep trouble. Gillespie says "I just don't know" whether Obama benefited from his handling of Hurricane Sandy GILLESPIE: You know, I just don't know. Governor Romney is closing very strong, with a big speech about the differences that would happen in the next four years. Dowd says Sandy moved the race DOWD: I actually do believe Sandy has had an effect. I think Monday morning, Mitt Romney would have won the popular vote and lost the Electoral College. Dowd identifies three signs a campaign is losing DOWD: ...every time you feel a losing campaign, these three things happen. The first thing happens is, don't believe - the public polls are wrong. That's the first sign of a campaign that's about to lose. The second thing, we're going to change the nature of the electorate, and you're not seeing it reflected in the polls. And the third thing is, the only poll that counts is Election Day. When you hear those things, you know you're about to lose. Brownstein says Bain story "resonates" in the Midwest BROWNSTEIN: The Bain story has a cultural and emotional resonance in the Midwest that it doesn't have in the Sun Belt, not as powerful in Colorado, Virginia. In Ohio, the idea of the rich guy coming to town, shutting down the factory and taking the profits just resonates. It detonates. Dowd believes "The Christie bear hug" had a greater effect on the race than Obama's response to Hurricane Sandy DOWD: The Christie bear hug, I actually believe, actually did more for the president in this slight movement, as I said, in his approval rating than actually even really his handling of the - of the hurricane. Brownstein warns of racial polarization BROWNSTEIN: Democrats clearly have a problem with whites. The incumbent president struggling to get 40 percent of the white votes. But Republicans are looking at losing, again, 80 percent or more of this growing non-white population. Mitt Romney, a candidate in a country that is now almost 40 percent non-white, is basically relying on whites for 90 percent of his vote. Will predicts a Romney win in Minnesota Will: But this year, there's a marriage amendment on the ballot that will bring out the evangelicals and I think could make the difference.
