More from Michelle Obama

• No, this election, and every election, is about who will have the power to shape our children for the next four or eight years of their lives.
• When someone is cruel, or acts like a bully, you don’t stoop to their level — no, our motto is, when they go low, we go high.
• With every word we utter, with every action we take, we know our kids are watching us. We as parents are their most important role models.
• A community is like a ship, everyone ought to be prepared to take the helm.
• Anyone can hold the helm when the sea is calm.
• This day does not belong to one man but to all. Let us together rebuild this world that we may share in the days of peace.
