I will accept that the Trump supporter ignorantly informed the Canadian of the possibility that he could vote with just a Villages ID and a signature. And as some Guest earlier pointed out, even an attempt to vote would not have succeeded. However the rest of the story does contain a very clear violation of Florida law.
It is a violation to solicit within 100 feet of the doorway to a polling location. There should have been signs placed indicating the boundary beyond which solicitation would be legal. If, as alleged, a Trump supporter was manning the door while soliciting votes, that is illegal. Certainly a person can help with the door but not with the purpose of representing the campaign or attempting to influence voters.
No person, political committee, or other group or organization may solicit voters inside the polling place or within 100 feet of the entrance to any polling place, a polling room where the polling place is also a polling room, an early voting site, or an office of the supervisor of elections where absentee ballots are requested and printed on demand for the convenience of electors who appear in person to request them. Before the opening of the polling place or early voting site, the clerk or supervisor shall designate the no-solicitation zone and mark the boundaries.
