Barack Obama is ahead by five points in the key state of Colorado – 51% to 46% – two weeks before Election Day, according to a new Fox News/Rasmussen Reports telephone survey. Three percent (3%) are undecided.

McCain was down by seven points last week. He last led Obama in mid-September.

Eleven percent (11%) of those who now support McCain say they could change their mind before voting. Fourteen percent (14%) of Obama supporters say the same.

Colorado was won by the Republicans in nine of the last ten presidential elections.

Obama has the support of 93% of Democrats while McCain is backed by 88% of Republicans. Unaffiliated voters favor Obama by 14 points.

The Republican has a seven-point lead among men but trails by 14 among women voters. White voters are closely divided but lean toward McCain. Non-white voters prefer Obama 67% to 31% (see full demographic crosstabs).

Fifty-four percent (54%) have a favorable view of McCain, while 44% regard him unfavorably. Obama is seen favorably by 56% and unfavorably by 43%.

Nationally, Obama has opened a steady lead over McCain in the Rasmussen Reports daily Presidential Tracking Poll and Electoral College projections. He now has the edge in every single state won by John Kerry four years ago. Of the states won by Bush in 2004, McCain is trailing in four, and five others are considered toss-ups.

Colorado voters are evenly divided on which candidate they trust more. They are similarly divided on which candidate they would seek advice from if faced with the toughest decision of their lives.

Forty-one percent (41%) list the economy as the most important issue in the election, and voters trust Obama over McCain on the economy 50% to 44%.

Twenty-one percent (21%) say national security is the most important electoral issue. McCain has the edge in trust on this issue, 51% to 45%.

Thirty-four percent (34%) would be Extremely comfortable with Obama as president, but 39% say they would be not at all comfortable with that outcome. Similarly, 26% say they would be Extremely comfortable with McCain in the White House versus 35% who would be not at all comfortable.

Colorado voters by a 41% to 28% margin think only Obama can bring real change to Washington compared to those who say only McCain is capable of that. Eighteen percent (18%) say both can, and 11% say neither.

But a plurality (48%) say Obama does not have the right experience to be president, while just 24% feel that way about McCain. Sixty-six percent (66%) say the Republican has the experience for the job, compared to 43% who believe that of his Democratic opponent.

Eighty-two percent (82%) of Colorado voters say they are Extremely interested in the presidential election, while just two percent (2%) say they are not at all interested.
