Although they are unable to vote in the election, they said they were excited to be among the crowds.

“It’s a once in a lifetime event,” one of the men said.

“I’m glad to be here while it’s happening.”

Another man said he had received some reactions of “horror, repulsion (and) disgust” after revealing he was campaigning for the Republican Candidate.
