A Data-Driven Way to Measure Partisanship

TL;DR: The Partisanship Score on the ChangeRoots App

This outlines the data used in the PoPa (Post Partisan) Score on the ChangeRoots App. We measure dollars donated, bipartisanship, whether candidates support an end to gerrymandering, and whether candidates support ranked choice voting (which has been proven to help depolarize the municipalities that use it).

How to incentivize wellbeing over political loyalty

Toxic partisans repel those in the other party with insults, contempt and political sabotage. This leads to less bipartisanship, which leads to fewer bills passed (legislative gridlock). On the other hand, post partisanship attracts legislative partners by respecting opposing views and working with anyone to improve wellbeing.

At ChangeRoots, we’ve developed a way to measure post partisanship.

Ratio of small donations to big donations

We hypothesize, on average, politicians who raise more money from small donors than big donors will act in way that prioritizes the wellbeing of all over political loyalty. By prioritizing raising small donations rather than large donations, they signal their prioritization of regular people over elites.

Support for Ranked Choice Voting

Research shows elections become less polarized after adopting something called ranked-choice voting rather than traditional winner-take-all voting. There is less negative campaigning, higher turnout and higher rates of people reporting they feel like the system is working for them.

Support ending gerrymandering

Gerrymandering is cheating. It’s abusing your power to draw congressional districts to keep your party in power. The good news, there is an effective way to end gerrymandering: appoint a nonpartisan group of experts (called independent commissions) to draw the districts instead of legislators. Studies show elections become less polarized when this happens and the district becomes more competitive, meaning nearly equal amounts of Republicans and Democrats vote for candidates.


Politicians who work with the other party the most — co-sponsoring bills together, voting together — are the least polarized candidates. They are often the ones making peace between parties and hammering out the solutions that end up getting passed.

Post Partisan Party

We consider politicians who raise money from small donors, support Ranked Choice Voting & independent commissions and work across the aisle post partisan. They exhibit the leadership we need right now. Our educated guess, more politicians acting post partisan means more bills getting passed that improve wellbeing for us all.

ChangeRoots makes it easy to reward post partisans while at the same time gives you an effective way to hold toxic partisans accountable for their actions.
