(CNN) - Republicans may be inching closer to a key Senate pickup in the swing state of Colorado.
Republican nominee Ken Buck now leads appointed Democratic incumbent Michael Bennet by 8 points among likely voters, 50 to 42 percent according to a new McClatchy-Marist poll.
Six percent of likely voters remain undecided, while 2 percent are backing someone else.
UPDATE: A source inside the Maes campaign tells CNN the embattled Republican nominee has decided to stay in the Colorado governor's race, despite increased pressure today for him to drop out.
(CNN) – Colorado Senate candidate Ken Buck is calling on fellow Republican Dan Maes to quit his bid for governor, the latest in a string of Colorado Republicans calling on the Tea Party favorite to step down before he is officially certified as the party's nominee later Friday.
"After having a lengthy conversation with Dan Maes, it is clear to me that Dan is struggling to determine the best path for his campaign, his family and for Colorado," said Buck in a statement. "I have decided that I can no longer support his candidacy for governor of Colorado."
Buck's statement comes after revelations Maes had embellished his resume about his business background and accused a Denver bike-sharing program of being an undercover plot orchestrated by the United Nations to advance an environmentalist agenda.
(CNN) Colorado Republican Senate nominee Ken Buck and his former challenger, Jane Norton, teamed up Wednesday, in the first joint-appearance by the two since the state's August 10 primary.
Norton, a former lieutenant governor, formally endorsed Buck at an event in suburban Denver.
"This is a really important election and we have an opportunity to take the Senate back. Ken is an extraordinary campaigner. He is going to go to Washington, he is going to vote to take our country back and to get us on sound financial footing. So I'm here to say, 'please support Ken.' I am doing it, and I hope all of you will," said Norton at the unity event, according to a press release from the Buck campaign.
(CNN) - The Republican nominee for Senate in Colorado said Wednesday that Republican frustration with both parties in Washington politics is driving grassroots victories over establishment candidates in GOP primaries around the country.
"I think Republicans realize that Republicans are every bit as much to blame for the mess that we are in in D.C. as the Democrats," Ken Buck told CNN's John King in an interview set to air at 7 p.m. on John King USA. "And we can't send this kind of Republican to Washington, D.C. to fix this mess."
Buck said he doesn't think the Republican Party has a national leader at the moment, and he expects the GOP's 2012 presidential nominee to be selected through "a wonderful process" whereby one contender emerges from a large pool of candidates-much like he has.
"I think we're going to see a number of people get into the race," Buck said. "We'll see who has the stamina, who has the financing, who has […] the grasp of the issues to attract voters."

(CNN) - With just over two weeks until Colorado's primary, a leading Republican Senate candidate who enjoys strong support from the Tea Party movement is apologizing for calling Tea Party activists "dumbasses."
The Denver Post and 9News reported Sunday that GOP Senate hopeful Ken Buck was caught on tape saying "will you tell those dumbasses at the Tea Party to stop asking questions about birth certificates while I'm on camera."
Buck, who was recorded without his permission by a Democratic operative while arriving at a campaign event last month in Crowley, Colorado, was referring to Tea Party activists who question the authenticity of President Barack Obama's birth certificate. As he continued to walk with the Democratic operative, Buck added "God, what am I supposed to do?"
The audio was obtained by the the Denver Post, which links to the audio clip in their on-line report, and 9News, a local news station in Denver.
(CNN) - Republican Colorado Senate candidate Jane Norton is seizing on opponent Ken Buck's now-infamous "high heels comment," launching a new ad Friday saying Buck's off-color remark shows "he'd fit right in" to the culture of Washington.
The ad – which was previewed by the campaign on YouTube Thursday - was quickly cut after a video surfaced showing Buck telling voters they should support him "because I do not wear high heels."
The comment, clearly made in jest, drew roaring laughter from the crowd though was quickly criticized by Democrats and Norton supporters as being inappropriate. But a spokesman for Buck says the gender issue is one Norton herself has repeatedly raised.
"The Norton campaign wants gender politics to be an issue in this campaign. They are the ones who have talked about it," spokesman Owen Loftus said.
(CNN) - Ken Buck, a Republican Senate candidate in Colorado, is causing a stir after recent comments asking voters for support "because I do not wear high heels."
The off-color remark that drew roaring laughter at a recent campaign event, came in response to an ad campaign from his GOP opponent in the primary race, former Lieutenant Gov. Jane Norton. In the ads, Norton says Buck is not "man enough" to attack her in person but instead lets third-party groups do it.
"She has questioned my manhood; I think it's fair to respond," says Buck to more laughter from the crowd. "I have cowboy boots on. They have real bull- on 'em. That's Weld County bull-, not Washington D.C. bull-."
(CNN) - Five weeks before Colorado's primary, Republican Senate candidate Ken Buck has landed a helpful endorsement.
The conservative candidate announced Tuesday that he's won the backing of FreedomWorks, a nonprofit organization that helps train volunteer activists and has provided some of the organization behind the Tea Party movement.
Buck, the district attorney in Weld county in north-central Colorado, is facing off against former Lt. Gov. Jane Norton for Colorado's GOP Senate nomination.
