PPP had ridiculous polls in the spring and early summer showing Obama leading by at or near double digits in Colorado and Virginia. They produced a huge number of other outliers. They may have been the most accurate pollster by the end of the campaign but they were far from it early on.
Given the final results, Obama leading by ten in Colorado right after the end of the highly damaging Republican primaries is hardly a surprise. Remember Romney's favorability ratings were in the toilet back in May/June.
