Seriously? PPP exaggerates Dem numbers early on. They may be accurate toward the end of a campaign, but they overstate Democrat percentages early in the campaign. I remember last summer seeing polls of the presidential campaign in several states that had Obama leading by a couple points, while PPP had polls with the same sample type in the same states that had Obama leading by almost double digits.
PPP over-predicts Democratic chances in a state that Democrats haven't abandoned in an election but eventually abandons. It does much the same for Republicans. Such is to be expected.
