(CNN) – Less than a week before Election Day, Colorado's heated Senate race remains a virtual dead heat, according to a new poll.
Democrats, however, may be pulling away in the race for governor - a contest in which Republicans once had high hopes.

Forty-seven percent of likely voters in the latest CNN/Time/Opinion Research Corporation survey now back Republican Senate nominee Ken Buck while 46 percent support incumbent Democrat Michael Bennet.
Seven percent are either backing someone else or offered no opinion.
Buck's one-point edge is well within the poll's sampling error.
One defining feature of the Senate race: the gender gap. Buck now leads Bennet by 12 points - 51 to 39 percent - among men, while Bennet holds a 12-point advantage - 54 to 42 percent - among women.
Also of note: the geographic divide.
"As frequently happens in Colorado politics, the race for the Senate will be decided in the Denver suburbs," said CNN Polling Director Keating Holland.
"Bennet has a two-to-one lead in Denver and Boulder counties, with Buck holding a sizeable lead in Eastern and Western Colorado and along the northern and southern parts of the Front Range.
But in the four-county area immediately surrounding Denver, the race is essentially tied, with Bennet holding an edge in older suburbs and Buck piling up big margins in exurban communities."
Bennet appears to be picking up ground; he trailed Buck by five points among likely voters in a September 17-21 CNN/Time/ORC poll.
While the candidates are virtually tied among likely voters, Bennet leads by five points, 49 to 44 percent, among the larger pool of registered voters.
Buck, the Weld County district attorney, was once a long shot in the battle for the GOP nomination, but thanks in part to support from some in the Tea Party movement, he defeated former Lt. Gov Jane Norton, who was recruited to run by national Republicans and was the early favorite in the race.
Bennet survived a spirited Democratic primary challenge from former Colorado House Speaker Andrew Romanoff. He was appointed early last year to replace Democratic Sen. Ken Salazar, who stepped down to serve as Interior Secretary in the Obama administration.
In the race for governor, 51 percent of likely voters now support Denver Mayor John Hickenlooper, the Democratic nominee. Thirty-seven percent support former congressman and 2008 GOP presidential candidate Tom Tancredo, who is running as the American Constitution Party's candidate.
Only 10 percent now back Republican nominee Dan Maes, who has been backed a number of Tea Party activists but struggled in the wake of a series of crippling campaign controversies.
National Republicans appear to have washed their hands of the race.
The CNN/Time/Opinion Research Corporation poll was conducted October 20-26, with 1,356 registered voters in Colorado, including 829 likely voters questioned by telephone. The survey's sampling error is plus or minus 2.5 percentage points for registered voters and 3.5 percentage points for likely voters.

Any reasonable reason why there is no response from ANYONE UNDER 50 in this poll?
Ignore these phony landline polls, which the so-called "liberal" media keep pushing in an apparent effort to discourage Dem voters. Average hard working Americans have seen the light, and recognize that the GOBP is a desperate cult, and rather than admit their articles of faith, such as deregulation, tax cuts for the ultrarich and unfair global trade, are PROVEN FAILURES, these nutjob extremists instead are seeking to spread their darkness of ignorance, fear, lies, and hate. We are the light, and our votes will send the teatards scuttling away, like cockroaches from the light. The Party of NO has no plan, no valid ideas and certainly no concern for Main St. America. They are massively out of touch with the poor and working class. We know this, and will vote accordingly. Then get your friends, family, neighbors and co-workers to vote for non-teatards as well.
@ Sharon, because they can not poll the younger crowd who has only cell phones! So they are missing a huge group of voters.
We, Liberals, haven't been polled. Most of us have cell phones, the polls are misleading. Also, the media has focused on the "angry masses" of the Koch-Teapublicans and are underestimating the Liberals, Moderates & Independents who have not forgotten how the U.S. got in the Great Recession!
Also, the polls and media underestimate the Latino vote which will be VOTING in record numbers this year against the Teapublicans who have demonized us!
I think it is you that have underestimated the average American citizen that is sick of what the Democrats and Republicans have done to our economy and our Nation. The big deal is that they now have seen the efforts of the Kenyan Marxist and decided that is far worse than anything a Republican carpet bagger can do to us...I think there will be a GIANT surprise to the libs on November 3...
Face it all you liberal minded people, no one wants Obama's brand of politics or the screw up Dems. All they are doing is turning this country into a model of western Europe which is really screwed up. Face it the Republicans are going to take this country back, if you do not like it then leave. I am a middle class working person and a proud Southern Republican. Tax and spend Democrats, that is all you can do. Obama is running this country into the ground, creating a huge out of control government. Forcing people to buy insurance like some 3rd world leader. You liberals are to stupid to see it behind your rose color glasses, of course they did not call you all, they want an honest opinion and an educated answer.
all you librals best go and vote come November. Vote the racist repos out. Move forward not backwards. You have to do more than talk and text. Vote
