Have you heard the one about the mom who decided to shake off her post-election blues by taking a walk through the woods in Chappaqua, only to bump into Bill and Hillary Clinton, walking their dog? The resulting photo has swept the internet, and offered some degree of solace to Clinton supporters. Meanwhile, Bernie Sanders die-hards are probably thinking, “Boy, I wouldn’t mind running into Bernie somewhere. I bet that guy could use a hug, too.” Don’t worry, Berners– you needn’t go trekking through the woods of Vermont to make it happen. (“Oh, hi, Bernie! I was just here for some maple syrup.”) This Monday, the candidate will be at the Barnes & Noble at 555 Fifth Avenue, in Midtown, posing with fans who’ve bought a copy of his new book, Our Revolution: A Future to Believe In.
