DENVER - 7NEWS projects that President Barack Obama has won Colorado.
Obama was leading Republican presidential nominee Mitt Romney 50 percent to 48 percent with 61 percent of the statewide vote counted.
Obama's Colorado victory was ensured as he won three bellwether counties -- Jefferson, Arapahoe and Larminer.
