DENVER, CO — Mere weeks after a small bird alighted on Democratic presidential candidate Bernie Sanders's lectern during a campaign speech in Oregon, nature visited the presidential race again. This time, a sizable vulture landed on the shoulder of front-runner Hillary Clinton in the middle of a fundraiser in Denver and deposited the lifeless carcass of a black rat at her feet. To the glee of a roaring crowd, Clinton graciously accepted the offering and consumed the rest of the carcass on stage.
