It's too close to call the state's Senate race.
A new Denver Post poll finds attorney general Ken Salazar with a slight lead over his Republican rival, Pete Coors.
Forty-six percent of 630 people say they'll vote for Salazar while 44 percent say they support Coors.
The poll has a 4 percent margin of error.
Nine percent say they are undecided while 1 percent supports other candidates.
