Trump has clearly neutered both houses of Congress and the Supreme Court. Welcome to a unitary government, with one god-emperor and no checks nor balances. It's going to be a wild two (few?) years.
Hence "few". Two if there are real elections in 2026, and the dems retake a majority. "few" if there aren't, or they don't -- in that case maybe 3-4 if term limits hold, or "who knows?" if as you say term limits don't apply, or Trump manages to put someone in place after him.
