Twice Broken: Constitutional Crisis, Institutional Erosion, and the Arc from Watergate to Trump

This dataset provides the Python code and instructions needed to visualize structural regime shifts in the Polity2 democracy scores for the United States between 1900 and 2020. The code focuses on detecting two major regime breaks in U.S. democracy:- The Watergate scandal (~1974)- The Trump era (~2015–2016) The upload contains:- **Google Collab Code.docx**: A Word document containing ready-to-run Python code.- **README.txt**: Instructions for running the code using Google Colab.- **p5v2018.xls**: The Polity5 dataset (needed to generate the democracy trend plots). ## Usage Instructions1. Open the `Google Collab Code.docx` file.2. Copy and paste the Python code into a new Google Colab notebook.3. Upload the `p5v2018.xls` file into your Google Colab session.4. Run all code cells. The code generates a clear time-series plot of Polity2 scores, highlighting major regime shifts in U.S. democratic performance. ## PurposeThis dataset supports the research project titled:> *Twice Broken: Constitutional Crisis, Institutional Erosion, and the Arc from Watergate to Trump* The visualization is intended for scholars, students, and researchers studying democratic erosion, constitutional crises, and U.S. political development. ## AuthorScott Brown (University of Puerto Rico at Río Piedras) ## LicenseCreative Commons Attribution 4.0 International (CC BY 4.0) ---
