"I honest to god haven't made my mind up about that yet", Biden told Matt Lauer and Savannah Guthrie.
"It's mostly the military men that are around him that have been the stable factors in the conduct of the foreign policy, a lot of bravado, but he hasn't changed a whole lot so far", Biden admitted - which is still not exactly naming something Trump is doing well, but bless his heart for trying.
"No, no, I'm not closing the door", Biden replied.
He added, "I'm a great respecter of fate, but who knows what the situation is going to be in a year and a half?"
"We're both hoping that both our parties generate some real energetic people who have the depth and the capacity to do it", Biden said of the pair.
Former U.S. Vice President Joe Biden speaks before presenting U.S. Senator John McCain (R-AZ) the 2017 Liberty Medal at the Independence Hall in Philadelphia, Pennsylvania, U.S., October 16, 2017. Although he campaigned for Clinton, he also has been critical after the Democrats' loss in 2016, which gave Republicans control of the White House in addition to their hold Congress.
He was asked about former Democratic National Committee chair Donna Brazile's book, which says she considered replacing Clinton with Biden because of health concerns. "No. 2, I wouldn't have taken it".
"She would have been a first-rate president, and at that point I had made the judgment well before that that I was not prepared to run for president".
"Oh gosh, I don't know, " he said. "I would never have done that".
