A close-run thing

The Writer's Almanac:

On this date in 1920, the 19th Amendment to the Constitution was ratified, giving women the right to vote. The first national constitutional amendment had been proposed in Congress in 1878, and in every Congress session after that. Finally, in 1919, it narrowly passed both houses of Congress and was sent to the states to be ratified. Most Southern states opposed the amendment, and on August 18, 1920, it all came down to Tennessee. The pro-amendment faction wore yellow roses in their lapels, and the "anti" faction wore red American Beauty roses. It was a close battle and the state legislature was tied 48 to 48. The decision came down to one vote: that of 24-year-old Harry Burn, the youngest state legislator. He had been expected to vote against it, but he had in his pocket a note from his mother, which read: "Dear Son: Hurrah, and vote for suffrage! Don't keep them in doubt. I noticed some of the speeches against. They were bitter. I have been watching to see how you stood, but have not noticed anything yet. Don't forget to be a good boy and help Mrs. Catt put the 'rat' in ratification. Your Mother." He voted in favor of the amendment.
