These may include personal charisma, communication skills, crises faced during their presidency, and broader social and cultural contexts. Additionally, this quote highlights how transient and subjective public views can be; what might seem like a groundbreaking accomplishment at one point in time could easily fade from collective memory or be overshadowed by other events.
