Former Vice President Joe Biden has thrown his hat into the 2020 presidential race, despite having come under criticism for being too touchy-feely with people during public events. Just Google "Joe Biden hugging" or "Joe Biden kissing" and you can kind of judge for yourself. While it probably shouldn't disqualify him any more than someone's great-aunt Eunice from running, it does indicate a bit of carelessness and letting emotions overrule logic in his behavior (like the current POTUS). He has after all challenged Trump to a fistfight which is pretty ridiculous in and of itself. That being said, Biden seems like a decent person and has experience. He also is a better choice than Trump for president - as are most living, breathing organisms. For now Biden needs to focus his energy on promoting fresh ideas if he want to succeed against his Democratic primary opponents.
