A reader points out the odd opening sentence of Barbra Streisand’s memo to the Democratic leadership. It says: “This is a key moment in our history. We cannot let the right wing roll back thirty years of social progress.” Thirty years, huh? So social progress began in 1971 under Richard Nixon, that great old liberal. And of those thirty years, eighteen were under Republican presidents. Maybe the impending catastrophe won’t be so terrible after all.
