(CNN) – Less than a week before the Democratic Party convenes in Denver to officially name its nominee, a new poll shows the typically-red state of Colorado shaping up as a battleground in the November election.
Sen. John McCain, the presumptive Republican nominee, leads his rival Sen. Barack Obama by 3 percentage points – 44 percent to 41 percent – in a new Rocky Mountain News/CBS 4 poll. Fifteen percent of those surveyed said they were unsure about their choice for president.
The poll of 500 registered voters conducted August 11-13 has a margin of error of plus or minus 4.4 percentage points, making the McCain-Obama race a virtual tie in Colorado.
