Voting rights and practical access are different. First-past-the-post and proportional rules can turn the same votes into different seat totals.

You have read about gaps between founding ideals and voting rights. Campaigns helped widen the United States franchise in stages. In 1920, the Nineteenth Amendment barred denying the vote because of sex. In 1971, the Twenty-sixth Amendment barred denying citizens aged 18 or older the vote because of age. The Silent Sentinels were women who picketed the White House for voting rights. Some were arrested and went on hunger strikes in prison. Their protests were part of a wider movement. Some women could already vote before 1920. Racial discrimination still blocked many voters after the amendment. *(drawing: These amendments changed legal protections. They did not remove every barrier to voting.)* In a single-seat district, first-past-the-post, or plurality voting, gives the seat to the candidate with the most votes. A majority is more than half. With 20 votes split 8, 7 and 5, the candidate with 8 wins without a majority. The smallest majority of 20 is 11. For any even total, divide by two, then add one to find the smallest majority. Vote share is party votes/total votes. Simplify fractions by dividing both numbers by the same factor. Percent means out of 100: divide party votes by total votes, then multiply by 100. A proportional rule aims for seat shares close to vote shares. Multiply seats by vote share. With 20 seats and 25 percent, 20 × 25/100 = 5 seats. For 2/3 of a total, divide by 3, then multiply by 2. We use exact whole seats; real systems need rounding and eligibility rules. **Example.** Compare five council seats using the same votes. Each of five districts has 6 votes for A and 4 for B. First-past-the-post gives A all 5 seats. Pooling the votes gives A 30 of 50 votes, or 60 percent, and B 40 percent. An exact proportional allocation gives A 5 × 60/100 = 3 seats and B 2. Count district winners for one rule; calculate pooled vote shares for the other. *(drawing: Each pair totals five seats. The counting rule changes their distribution without changing the votes.)* Having the right to vote does not make voting easy. Long journeys, queues and hours that clash with work can stop eligible voters from voting. Reducing these barriers can help turnout, the share of eligible voters who vote. It does not guarantee higher turnout, because other conditions also matter. **Recap.** Voting rights and access both matter. First-past-the-post counts district winners; a proportional allocation uses vote shares to distribute seats. *Lesson, questions and flashcards written for this dataset.
