But at the Presidential level, the candidates personalities and characteristics like race in 08 can swing a lot of votes.

Refers to the Partisan Voting Index (PVI) as used by Charlie Cook, Washingtons foremost political handicapper. If the site only uses SVI, then we are basing our read of the partisan breakdown on a single cycle in which the GOP ticket was headed by a guy their base did not much care for and did not have anywhere close to an even playing field in financial resources as the economy crumbled in spectacular fashion under a sitting president of his party. St. Johns Legal Studies Research Paper No. First introduced in 1997, the Cook PVI measures how each state and district performs at the presidential level compared to the nation as a whole. According to Politico, the PVI is designed to "provide a quick overall assessment of generic partisan strength in a congressional district. Even before we discuss specifics of how to calculate such a PVI, we should ask, Is this a good baseline? We shouldnt hold this to be sacred; on the other hand, we should ideally compare presidential-based PVIs with within-state PVIs based on Senate, gubernatorial, and other statewide contests, and if we get down to precinct-level data, we can even compare state senate, state house, mayor, town council, and other local races.

Either way, PVI or SVI, you get a nice take on whether party nominee is overachieving or under-performing in comparison to the top of his/her ticket.

Before that, we go all the way back to 1964 for us and 1972 for them. By the most stringent measure, the CPI was accurate in over 94% of legislative races. That would make it a more accurate gauge of true feeling, and it would be relatively easy to do. I realize the point is to compare the district to the national average, but Im not sure how useful that information is when predicting whos going to win in a district. Id be curious to know what sort of justifications or rationales anyone can come up with for the status quo. The PVIs for states are calculated based on the 2004 and 2008 presidential election.
