The National Election Poll is a collaborative effort led by major news agencies and conducted by Edison Research. Working under the direction of Prof. Marc Meredith (UPenn PSCI; NBC Decision Desk) with the support of Prof. John Lapinksi (UPenn PSCI & Fox-Fels; Director of Elections Unit, NBC News), I used historical data and national benchmarks to evaluate the performance of a new weighting scheme in matching real election returns. Read a full description of the project here.


This set of tables allows for a comparison between the unweighted data and the weighted data with or without imputations. As a result of this project, the NEP is now weighted using education.
