Data Methodology
A technical overview of the GOP Data Center scoring criteria for Jason Cahill and Texas's 21st Congressional District.
01. SCORE AGGREGATION
The Democrat Voting Score is the primary metric used by the GOP Data Center to quantify legislative alignment. This index is calculated by cross-referencing floor votes cast by candidates against established caucus platforms. A higher score indicates a consistent pattern of voting with the opposition party on critical fiscal and social legislation.
02. LEGISLATIVE CONTEXT
Weighting is applied to votes based on their impact. Major appropriations bills, tax adjustments, and constitutional amendments carry significant weight, while minor procedural resolutions are excluded. This ensures the data reflects substantive policy shifts rather than routine administrative business.
03. SOURCE VERIFICATION
All data points are extracted from the Texas Legislative Council and official House Journals. The GOP Data Center performs a secondary audit of each vote to verify that record-votes match the intent described in legislative summaries, maintaining data integrity for all electoral rankings.
Disclaimer: Methodology and scores are subject to quarterly revisions as new legislative sessions conclude and fresh data becomes available through verified GOP Data Center sources.
