Legislative Floor Assumptions

Axios Reporting Grounding: Rep. Steve Scalise (R-La.) pegged the party's election target at 225 seats—a net gain of 5 to 7 seats from their slim working majority.

Floor Defection Math: When the full 435 members vote, 218 votes are required. A 225-seat conference can sustain up to 7 GOP defections on party-line roll calls before stalling at 217.

Tossup Dynamics: Currently, approximately 32 congressional districts fall into non-partisan tossup categories, determining which party secures speaker leverage.

Methodology Note: Calculations assume a full 435-member voting House without vacancies. Floor majorities require 218 votes. High-water projections reflect Axios report on House GOP leadership planning. All calculations execute locally in-browser.
