That is most assuredly NOT the case.
U.S. Senators and U.S. Congressmen are not subject to recall. Period. The U.S. Constitution makes no provision for this action and, upon election, they are subject to federal law, not state law.
the us constitution has zero language in it that prohibits recall of sentors and representatives.
it explains the enumerated powers fedgov has. there is no enumerated power reserving this power to fedgov.
further nothing in it specifically tells states they cannot recall their electors.
therefore this recall power is a tenth amendment issue, with this ability remaining residing with the people and the states.
