Former Vice President Joe Biden drops major hint of a 2020 presidential bid during a speech at the firefighters convention during wild applause: “Save it a little longer, I might need it in a few weeks.”

Biden told the crowd: “I appreciate the energy you showed when I got up here. Save it a little longer, I might need it in a few weeks.”

Biden, who leads in several polls, is being urged to throw his hat in the ring for the upcoming presidential election. He leads the field of Democratic candidates by a wide margin in a recent Michigan poll, as well as leading in Iowa and New Hampshire polls.
