Democratic presidential nominee Barack Obama is leading Colorado by 7 percentage points over Republican opponent John McCain, according to a Time/CNN poll released Wednesday.

Obama led McCain in Colorado 50-43 in the poll; Libertarian presidential nominee Bob Barr polled 3 percent, independent candidate Ralph Nader polled 3 percent, and Green Party nominee Cynthia McKinney polled 1 percent.

Asked to choose just between the Republican and Democratic presidential tickets, 51 percent of those polled said they supported Obama  and running mate Joe Biden;  47 percent chose McCain and his vice presidential nominee Sarah Palin.

The poll was conducted Oct. 11-14 among 762 likely voters in Colorado. The survey's margin of error was +/- 3.5 percent.

A TIME/CNN/Opinion Research Corporation poll released today suggests that independent candidates could swing the election in Colorado.
