The Wall Street Journal just released a new poll about how Joe Biden's age might affect his electability, and found "Biden's age may be a growing problem for his reelection." According to the poll, most Americans think he's too old. Joe Biden is 80 years old. He'll be 81 in November and would be 86 by the end of a second term if he wins reelection. He's already the oldest president in U.S. history.
