Joe Biden's exit, talk of the glass ceiling, a nod to Gaza protesters. Takeaways from DNC's Day 1

The Democratic National Convention’s first night has showcased speeches from the last Democrat to lose to Donald Trump and the last one to beat him. Hillary Clinton spoke hopefully of finally breaking the “glass ceiling” to elect a female president. Joe Biden laced into Trump and directly acknowledged the concerns of protesters against the war in Gaza who demonstrated a few blocks from the convention hall. And Vice President Kamala Harris told Biden, “We are forever grateful to you.”
