The best known political aggregator website, RealClearPolitics.com, maintains the most respected and frequently used polling averages. It lists 34 polls conducted in Colorado since February on the presidential race horse question. Mitt Romney has only been ahead six times, but three have been in the last week.
Because of that, Romney is now ahead in Colorado by a fraction (0.5) of a point over Barack Obama for the first time this year. Obama has also lost his national lead six days after his weak debate performance in Denver.
