The 2020 race is dominated by 70-somethings as the top three Democrats in recent primary polls are all septuagenarians. Both former Vice President Joe Biden, 76, and Sen. Bernie Sanders, 78, would be the oldest elected president. Sen. Elizabeth Warren is 70. No other Democratic candidate younger than 70 is in double digits, according to a new CNN poll. President Trump is 73 years old, and he became the oldest first-term US president when he was inaugurated at age 70. https://cnn.it/34EhIj6 | CNN
