Joshua Green: “Colorado’s Senate race has become a presidential campaign in miniature, with two strong candidates who are both career politicians facing off over mainly national issues, as billionaires on the left (Steyer) and the right (the Koch brothers) saturate the airwaves with tens of millions of dollars’ worth of attack ads.”

“Politically, Colorado is a slightly ­exaggerated version of America. Because the state makes it so easy to place initiatives on the ballot, it’s a testing ground for highly charged national issues.”

“The great thing about not being president anymore is you can say whatever you want — unless your wife might run for something.”

— Bill Clinton, quoted by NBC News.

A new SurveyUSA poll in Georgia shows David Perdue (R) leading Michelle Nunn (D) by just one point in the U.S. Senate race, 46% to 45%.

“I cannot predict precisely what the rate would be at the end of one year. I can tell you that over a period of four years, by a virtue of the polices that we put in place, we get the unemployment rate down to 6 percent, perhaps a little lower.”

— Mitt Romney, quoted by MSNBC in May 2012, noting the unemployment rate is already down to 5.9% without Romney’s policies.

Wall Street Journal: “The backdrop of this fall’s voting is a mood of voter anger over the status quo, polls suggest. Just one month before the Nov. 4 election, it isn’t even clear what exactly the midterm contests are about. No single issue dominates, except unhappiness with the established order.”

A new Survey USA poll in South Dakota finds Mike Rounds (R) barely leading a three-way Senate race with 35%, followed by Larry Pressler (I) at 32% and Rick Weiland (D) at 28%.

Jon Huntsman told Politico that he would not run in 2016 and has no plans to run for governor again.

Said Huntsman: “I can’t describe a pathway through the early primary states up to Super Tuesday, and if you can’t find that pathway or describe what that pathway is, then you had [better] not be in the race.”

New York Times: “When he soared to victory by almost 10 million votes in 2008, President Obama won in states like Virginia that Democratic candidates had not captured since 1964. He was trumpeted as a transformational leader who remade American politics by creating a new electoral map and a diverse voter coalition to shape the Democratic Party for the 21st century.”

“But for now he has been reduced to something else: an isolated political figure who is viewed as a liability to Democrats in the very states where voters by the thousands had once stood to cheer him.”

Nate Cohn: “No other plausibly competitive state has seen a more favorable shift for Democrats in the racial composition of eligible voters over the last decade. The pace of demographic change is so fast that Michelle Nunn, a Democrat, is locked in a tight race against the Republican David Perdue for an open Senate seat — even with an off-year electorate that is favorable for the G.O.P.”

“The pace of demographic change might even be fast enough to outpace the polls.”

A new SurveyUSA poll in Kansas finds Greg Orman (I) leads Pat Roberts (R) in the U.S. Senate race by five points, 47% to 42%.
