Democratic Performance Index

The NCEC’s Democratic Performance Index (DPI) is a fundamental measure on which campaigns base their decision-making, evaluate models, target precincts, and build paths to victory. DPI is a granular, moving average of actual candidate performance. We calculate DPI for every state at the precinct level—the most detailed level at which election results are recorded.

The strength of DPI is that it is so closely anchored to direct measurement of what actually happened. Even with the upsets of 2016, DPI proved to be robust and accurate predictor of candidate performance (see 2016 analysis):

“In the 30 most competitive House races—where we devoted most of our attention—the mean discrepancy between the pre-election Democratic Performance and the outcome was a closely-correlated 3.0 percentage points.”
