Republican majorities in both chambers of Congress following the 2024 elections and 2026 midterms represent the primary barrier to impeachment and removal of President Trump before 2028. House impeachment requires only a simple majority, yet unified GOP control reduces the likelihood of advancing articles absent bipartisan consensus, which has not materialized. Senate conviction demands a two-thirds supermajority, a threshold rarely crossed along partisan lines and historically unmet for removal. No recent legislative votes, committee actions, or official announcements have signaled sufficient cross-aisle momentum or procedural momentum. Trader consensus reflected in the 82.5% probability on "No" aligns with these structural and institutional factors rather than short-term polling shifts.
