Susan Shillinglaw at The Washington Post writes 75 years after ‘The Grapes of Wrath,’ we need Ma Joad in the White House: President Ma Joad wouldn’t cut food stamps. She wouldn’t deny education to immigrant children. She wouldn’t trim funds for the homeless. She would remind each American that lending a hand to those at the bottom is a quality of the species, Homo sapiens. She would fire up the country with collective energy, too.
