(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.
The race is much tighter among registered voters as a whole, where Bennett is clinging to a statistically insignificant 1-point lead, 41 to 40 percent.
The results are similar to a CNN/TIME/Opinion Research Corporation poll released September 22, which showed Buck leading Bennett by 5 points, 49 to 44 percent among likely voters. Bennett held a 47 to 44 percent lead among registered voters in the CNN/TIME/ORC poll.
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.
The McClatchy-Marist poll was conducted September 26-28 with 822 registered voters in Colorado, including 537 likely voters questioned by telephone. The survey's sampling error is plus or minus 4.5 percentage points for registered voters and 3.5 percentage points for likely voters.
After seeing all the damage that the democrats can do in such a short amount of time, I've decided that the only way our country can survive is to vote in the most honest and qualified republicans.
I've heard democrats actually state that they are 'planing/supporting' minor candidates in the Constitution and Libertarian parties in the hope of peeling off votes (5% – 7%) from republicans this election in the hopes of retaining their position. Not only is this dishonest, but shows how much democrats crave power.
I've voted as an independent all my life.... until this election.
Say BYE BYE Bennet! Maybe Obozo can find you one of those imaginery "green jobs" on November 3rd?
When I came in this country in sixties I thought that Americans are most educated people in the world, but now I doubt if they know what is good or bad for them.
They are voting against their own benefit, including women's whose freedom will be totally wiped out with Ken buck if he get elected.
How a professional woman can jeopadize her carrier for nine month to give birth to a rapist child?
A vote for Bennett would be a vote for Obama and his failed Socialist agenda - with high unemployment, high deficits, and high taxes.
A vote for Buck would be a vote for Constitutional government - with renewed freedom and liberty, lower taxes, and more economic opportunity.
The choice is clear: vote for America, vote Republican
The problem is, there aren't any honest and qualified repubs!!
Coloradans...please don't go to the dark side. Vote for Bennett. Vote for sanity in the Senate.
Well the liberals got their hope and change in the last election and America has rejected it. Come this November mid terms and November 2012 one heck of alot of tax and spend liberals will be sent packing from DC. Now that is Hope and Change this country can believe in. Hip Hip Hoorah
good ,,bennet was just another rubber stamp for obama , reid and pelosi....
Just remember Colorado voters, if you liked the ditch the GOBPbaggers drove us into last time, you're gonna LOVE the canyon they're aiming for now!
