Calvin Coolidge – 141.6
Vice President Calvin Coolidge was the next in line after President Warren Harding’s tragic death in 1923. The next year, he was elected president and served until 1929. He had a 141.6 IQ. He was a popular politician because he advocated for a laissez-faire foreign policy and small government. His kind attitude belied his deep commitment to racial equality and social rights. He didn’t always get along with his coworkers, particularly when he pushed to make lynching a federal crime. In addition, his government passed the Indian Citizenship Act, which granted citizenship to Native Americans residing on reservations.
