Have there been an US President, with no affiliation to either politics parties?
All the previous answers are correct. Washington was not affiliated with any party because they really hadn't formed yet. But they soon did right soon after his election when Hamilton, Adams, and others started the Federalist party and Jefferson, Madison, and others started the "Republican" party that eventually evolved to the Democratic party of today. The Federalists withered away and morphed into the Whigs who were around until the Civil War. Today's Republican part was started right before the Civil War.
