Bridge Grades is a report card for Congress.
Our systems grade Congress on how collaboratively or divisively they govern by compiling objective 3rd-party data into a score that sorts legislative “bridgers” from “dividers” based on what a person says (public statements, speeches, social media), and what a person does (authoring and sponsoring cross-partisan bills).
Bridge Grades offers American citizens an alternative lens to evaluate and assess the performance of our United States legislators beyond ideology or party affiliation.
We believe toxic polarization and hyper-partisanship is holding us back. We are inspired to introduce incentive for legislators to seek collaborative win-win solutions for our common interests. Our multi-year quest is to build Bridge Grades into a transparent, open source, crowdsourced, and independently governed system protected from special interests. Durable and self-sustaining, we aim to build Bridge Grades into a public utility that educates citizens by offering an easy way to sort Congressional bridgers from dividers, while nudging incentives for House Representatives and Senators to engage in more collaborative governance for our common interests.
A project of non-partisan Mediators Foundation,Bridge Grades is deliberately an educational resource and neither participates in campaigns nor endorses specific candidates.
Created by Brad Porteus and built through a collaboration of a wide roster of contributors, Bridge Grades is a project of non-profit organization Mediators Foundation of Boulder, Colorado.
Grading rubric contributors
In 2024 and 2025, the development of the Bridge Grades rubric and methodology has been a collaboration with IU Innovates (Indiana University’s Data Science as a Service) thanks to program sponsor Dr. David Wild at Luddy, program design mentor Kyle Stirling, Maria Aroca, and more than a dozen Masters candidates across two cohorts (Liz, Andy, Tyler, Siddharth, Utkarsh, Sai, Paul, Jason, Jaimie, Katrina, Bryant, Sanjana, Joy, Abubakar).
Special thank you to Universidad del Norte, Data Science undergraduate phenoms Emanuel Carbonell Naranjo and Zharick Molina for stitching it all together starting in early 2025 under Maria Aroca’s exemplary leadership and oversight.
Web, database, search, and other technical development led by Serge Scevenels, who serves as fractional CTO for Bridge Grades since late 2025.
