The ONLY closely contested, partisan race was the VA Governor's race, unless Biden counts the Atlantic City, NJ mayor's race (which no one does);  Biden was a bit of joke as vice president, which is why he didn't run in 2016. He will be nearly 80 yrs old by election day 2020, older than Pres Reagan was when he Left office. He also has a problem in the post-Weinstein era, because of his habit of touching & grabbing women, which has been captured in many photos. In a contested race, you can expect this to be raised by his opponents.
