As recently as 08 the state of California refused to allow a candidate on the ballot due to constitutional ineligibility.
Socialist party Candidate Roger Calero was removed from the ballot due to the fact that he isn’t a citizen of this country. Unfortunately he was allowed on the ballot in several other states.
States are going to have to contend with an anti-Constitution/anti-America apparatus never before seen: the Democratic Party with the Impostor-Marxist at the helm and leftist courts emboldened by these astonishing turn of events.
