Joe Biden 'Thinking About' Running For President, Son Beau Biden Says

Vice President Joe Biden is well aware that the loudest rumblings about the 2016 presidential election are currently coming from supporters of former Secretary of State Hillary Clinton -- he experienced their enthusiasm firsthand last week.

Yet while the Clinton speculation already appears to have kicked into overdrive, Biden's son, Delaware Attorney General Beau Biden, recently told The New York Times that his father isn't closing any doors, especially with Clinton still maintaining that her career in public office is over.

“It’s no secret that he’s thinking about this,” the younger Biden said. “I’m glad he’s thinking about this. But he hasn’t made up his mind.”

Clinton, on the other hand, has said her mind is made up. But many supporters believe she has left the door open for a 2016 run. Last week, she added fuel to the fire, announcing a book deal and delivering high-profile speeches in New York and Washington, D.C.
