Mark Levin: Reader says not so fast Mark
Mark was shown where he made a mistake in stating in a footnote that delegates from Vermont belatedly attended the constitutional convention in Philadelphia in 1787. In reality, Vermont was not even a state until 1791. Before that it was a disputed territory between New Hampshire and New York. So Vermonters were not asked to nor were they qualified to attend the Philadelphia convention. He gave his challenger no credit for reading his book carefully and bringing this non-trivial mistake to his attention. He then refused to sign the book on the page where the footnote appeared and showed distinct signs of impatience and annoyance when he opened the front of the book and began to sign it.
At this point, Mark was challenged about Cruz’s eligiblity. But the challenge did not happen as Mark said it did. The challenger asked this: “Under what possible definition of the term natural-born Citizen does your friend Ted Cruz qualify to be president?” At this same time the challenger placed an annotated copy of an earlier TheRidgewoodBlog posting repeating CNN’s recent article questioning Cruz’s eligibility, and was pointing at the document. After cursing at the challenger , Mark replied: “I never said he was a natural-born Citizen.”, upon which his challenger said: “But you must be a natural-born Citizen to be President!”. Mark then said: “No you don’t!”, and the challenger said “Yes, you do. Read the Constitution.” Levin was showing no signs of changing his tune. The challenger then turned around and left the booksigning. There was no time during any of this dialogue for Mark to ruminate on the challenger’s motivations or talk about Canada or Cruz’s mother or anything like what he said on his Radio program
