Highest ROI Senate 2020

Goal thermometer

This page allows you to quickly and easily donate to the Senatorial races that appear to be highest ROI based on simple metrics that capture two factors:

  1. Competitiveness: how close the race is, as measured by modelled estimates (538 Deluxe) and averages of recent high quality polling (last three polls on 538 with B- or higher quality)
  2. Impact of marginal dollar: which candidates appear to have greatest need for marginal dollars, based on population adjusted financial resources ($/voting age pop) and relative funding compared to Republican competitors (simple ratio)


Based on these criteria the following candidates will be supported by your donation:

  • Greenfield (Iowa)
  • Ossoff (Georgia)
  • Bullock (Montana)
  • Gross (Alaska)
  • Harrison (S Carolina)


Detailed methodology and data utilized can be accessed here.
