The proposed SVI, comparing numbers within one election, doesnt solve this problem either. Why do states in the North perform better than states elsewhere in terms of education?

I agree with the majority sentiment that it seems to make more sense to compare 2000 district performance with 2000 nationwide performance, not 2004 nationwide performance. I dont think Cooks PVI or this proposed SVI would be as useful a measurement as they could be. Another option would be to average the House, Senate, and Presidential numbers, so we dont rely exclusively on the Presidential race to define a districts lean.

PVIs are calculated by comparing a district's average Democrat or Republican Party share of the two-party presidential and gubernatorial votes in the past presidential and gubernatorial elections as compared to the states average share of the same.The statewide average in 2012 was approximately 54.57% Democrat to 45.43% Republican.For example, in Washingtons 43rd Legislative District, Democrat candidates won an average 85.85% of the two-party share in the 2012 presidential and gubernatorial elections, respectively.Comparing the average of those two results (85.85%) against the average statewide share of the same (54.57%), the district voted approximately 31 percentage points more Democrat, or D+31. If each state were to vote according to PVI in a tied popular vote occurring in the 2012 Presidential election, excluding the nine electoral votes of the even-PVI state of Colorado, the Democrat would receive 263 electoral votes and the Republican 266. 1 COOK PARTISAN VOTING INDEX.
