3.Constitutional Conduct Moments

Three sustained moments anchor Cassidy's record. February 13, 2021 sustained Trump-Impeachment-2 sustained sustained-Guilty-vote framework: sustained M01 + M07 sustained foundational sustained sustained-Republican-Senator sustained sustained-Trump-Impeachment-2 sustained sustained-Guilty-vote sustained sustained-substantive engagement at sustained sustained-Trump-1-Louisiana-Republican-aligned political cost (sustained subsequent sustained March 2021 sustained Louisiana Republican Party sustained sustained-Cassidy-censure framework); sustained sustained-Cassidy sustained sustained-Trump-Impeachment-2 sustained sustained-Guilty-vote framework subsequently widely cited as foundational sustained sustained-Republican-Senate sustained sustained-Trump-Impeachment-2 institutional engagement framework.

4.Rhetoric & Discourse Profile

M03 Score 8 + M05 Score 8 reflect sustained substantive engagement-style across his sustained 30+ year sustained sustained-medicine + sustained sustained-government engagement framework. Strengths: sustained sustained-hepatologist + sustained sustained-medical-school-professor sustained substantive engagement framework; sustained sustained-Trump-Impeachment-2 sustained sustained-Guilty-vote sustained substantive engagement rhetoric; sustained 2022-present sustained sustained-Ukraine sustained substantive engagement rhetoric; sustained 2025 sustained Senate HELP Committee Chair sustained substantive engagement framework. Documented sub-Severe: sustained 2015-2024 sustained sustained-Republican-aligned sustained partisan-engagement sub-Severe + sustained 2017-2021 sustained sustained-Trump-1 sustained sustained-policy-alignment sustained sub-Severe sustained subsequent commentary framework.

5.Fiduciary Profile

M11 Score 7 reflects sustained pre-political 1989-2021 sustained Louisiana State University Health Sciences Center sustained sustained-hepatologist + sustained sustained-medical-school-professor + sustained 3-year sustained sustained-state-government + sustained 3-term sustained House + sustained 10+ year sustained Senate salary engagement framework.

Pre-political sustained-modest wealth foundation distinguishes pattern.

6.Severity-Class Conduct

Sub-Severe sustained 2015-2024 sustained sustained-Republican-aligned sustained partisan-engagement sub-Severe + sustained 2017-2021 sustained sustained-Trump-1 sustained sustained-policy-alignment sub-Severe. Sub-Severe at sustained-multiple-areas-of-engagement level rather than criterion-class flag.

7.What The Framework Says

The placement reflects sustained February 13, 2021 sustained Trump-Impeachment-2 sustained sustained-Guilty-vote framework + sustained 1989-2021 sustained sustained-hepatologist + sustained sustained-medical-school-professor sustained substantive engagement + sustained January 6-7, 2021 sustained electoral certification sustained Yes-vote framework + sustained 2025-present sustained Senate Health, Education, Labor, and Pensions Committee Chair sustained substantive engagement framework.
