Who is the best candidate running for president right now?

Vice President Joe Biden announced Wednesday he will not be a candidate for president in 2016, sparing Democrats from a shake-up in the race for the White House and removing a potential stumbling block for Hillary Clinton.

The vice president’s decision comes after a long, and very public, struggle with whether or not to make a third run for the White House. Overcome with grief after the death of his eldest son, Beau, in May from brain cancer, at many times Biden seemed far from ready for the rigors of the campaign trail. (NPR)
