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? If the site uses only PVI, we overstate GOP strength based on the Bush 2004 GOTV operation which no longer exists and ignore the shift in party ID over the last few years.

Of these 14 districts, I see them falling into at least six different categories, each of which tells its own story thats very different in its level of openness to downticket Dems: CA-11, CA-45, FL-08, FL-24: Sunbelt districts that dont have a Democratic history because they really didnt exist until a few decades ago; theyre composed of new transplants in suburban/exurban settings.

Read More Map Hardly a day hardly a post goes by here at the Swing State Project without a reference to the Cook Political Reports Partisan Vote Index, or PVI for short. What we need is a way to estimate a sort of generic D vs. R matchup for each district (or state, or state senate/house district, or county, or town, or even precinct).

The PVIs for states are calculated based on the 2004 and 2008 presidential election. 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. I think the SVI is better. 2311 Wilson Blvd Third Floor, Arlington, VA 22201 | Contact Us. Of course, my preference is an Excel sheet listing vote totals by office (prez, gov and CD) side-by-side over the last several cycles broken down by county. I live in a house thats over 40 years old that was constructed on somewhat marshy soil.

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

Colorado would decide the election, resulting in a 272-266 Democratic win or a 275-263 Republican win. David Nir of the Swing State Project advocated a change to the new formula, and Charlie Cook agreed, wanting an "apples to apples" comparison. To ensure consistency, all 2021 (pre-redistricting) and 2022 (post-redistricting) PVI scores cited in this report reflect the new formula. The PVIs for states are calculated based on the results of the U.S. presidential elections in 2016 and 2020. There is no magic bullet, no algorithm which will tell us by plugging in data which district can be swung with a little effort. University of Wisconsin Law SchoolView posts , Vice Dean for Faculty

I think we should use a dual system of level (SVI) and parallel (Cook PVI). As we head into next years election, lets take a look at what we are likely to see based on how partisan the states really are. A Cook PVI score of D+2, for example, means that in the 2016 and 2020 presidential elections, the state or district performed about two points more Democratic in terms of two-party vote share than the nation did as a whole, while a score of R+4 means the state or district performed about four points more Republican. Off-year cycles are very different beasts when it comes to TO, especially in states which have their gubernatorial elections in Presidential years (and the usual problem of getting out Leap Year Dems generally).

Ballotpedia does not curate or endorse these articles. 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. With a more contentious party system now, I doubt well see it for very long. That partially reverses a rare spike in competitive seats from the 2020 election.

Several states in this region, including North Dakota, South Dakota, and Wyoming, only have one congressional district effectively making the PVI ranking statewide.
