Vice President Joe Biden still has the presidential itch. The one-time 2008 competitor to Barack Obama said this week: "I am never ready to close the door on anything...I am intent on reelecting Barack Obama president of the United States of America. The rest will take care of itself." He couldn't run until 2016, when he will be 74. If he won at that age, he would be the oldest candidate ever to win the presidency.
This poll is now closed, but the debate continues in the comments section.
