Caren, Biden's VP, doesn't figure that much in folk's minds. If they can't imagine an eighty-six-year-old Joe in Oval Office dotage, they can't imagine a power transfer to a vice president, whoever that is.
Biden continuing creates significant risk for Democrats, America, and the world. Stepping aside can allow a younger and more talented at taking us into the future apart from winning in 2024.
Biden has likely hit his zenith of appreciation and accomplishments. More people must paint this reality to him and Jill and some excellent, fulfilling, and enjoyable activities for a former president.
Many thanks. Best.
