Harry Belafonte had a saying about preaching to the choir. There’s a time and place for everything, he advised. If you never preach to the choir, what keeps them singing? In this spirit, Barack and Michelle Obama are perfect cheerleaders and mascots for Kamala Harris. They won’t be difference makers in battleground states but, for a majority of the electorate nostalgic for simpler times, the Obamas are just what the doctor ordered. With only two weeks left before the election, though, we’ll need people to take the stage and convince those not already in the choir that there’s a reason to show up in the first place.
