Joe Biden went to Puerto Rico yesterday to survey the damage caused by Hurricane Fiona.  This should have been an easy trip for “Uncle Joe,” a great chance to show off his legendary compassion and turn the page from “Where’s Jackie?”  Not a chance! Biden’s been on the public stage for decades, and yet we keep learning new things about him.  He told us yesterday that he was politically “raised by the Puerto Rican community” in Delaware.  What?!
