While Hillary Clinton and Bernie Sanders battle it out for the Democratic nomination, Joe Biden could be the dark horse who will surprise everyone and snatch it while the two frontrunners aren’t looking.

For the last several months, the two Democratic frontrunners, Hillary Clinton and Bernie Sanders, have been essentially fighting a two-candidate battle, with virtually no opposition from the other Democratic challengers. And, when the media hasn’t been covering the crowded Republican field (with Trump in the lead), these two candidates have been the only ones receiving true coverage on the Democratic side. It’s almost as if it’s definite the nomination will go to one of the two. It has to, right?

Wrong. There’s still a chance someone else could take the nomination—and I’m not talking about Lincoln Chafee. I’m talking about the Vice President of the United States of America, Joseph Robinette “Joe” Biden, Jr.

It’s no secret: Joe Biden has had his eye on the presidency for a long time. In 1988, he unsuccessfully made a bid for the Democratic nomination. Biden’s campaign was plagued with infighting between his campaign staff and his repeated plagiarizing of other politicians’ speeches (which brought to light several other instances of plagiarism throughout his career, including from law school), which led to his falling behind in the polls in August 1987. By September, he was forced to withdraw from the race.

In early 1988, he suffered from a life-threatening brain aneurysm and underwent surgery to correct the problem. The Biden family took the early withdrawal from the ’88 race as a “blessing in disguise,” as, if he were still campaigning, he may not have sought help and would’ve died as a result.

After the 1988 race, Biden withdrew from presidential politics and continued serving on the Senate Judiciary Committee—which he chaired until 1995. It wasn’t until 2008 that Biden again pursued the Democratic nomination for the presidency. That attempt wasn’t as successful as his 1988 bid. Biden wasn’t able to fundraise nearly as well as he had 20 years earlier. Along the campaign trail, he made several rather derogatory, controversial, and questionable remarks, such as his calling Obama a “storybook” of a man. With his campaign being unable to gain momentum, Biden withdrew from the race on January 3, 2008.

Later that year, Biden accepted Barack Obama’s vice presidential nomination and on January 20, 2009, he was sworn in as the Vice President of the United States, a position in which he has served for nearly the past seven years.

It’s not uncommon for the Vice President to be the candidate for his boss. A Vice President has experience that makes it an almost logical choice as the next president. Historical instances of this “promotion” are Martin Van Buren, William H. Taft, Harry Truman, and George H.W. Bush. Presidents in the past have picked—or, rather, supported—the Vice President as almost a handpicked successor.

If Joe Biden were to throw his hat into the ring, he would be one of the most experienced people on either side, if not the most experienced. He served in the Senate for 36 years (from 1973-2009). While in the Senate, he chaired the Foreign Relations Committee three separate times and the Judiciary Committee for nearly 10 years. On top of his legislative experience, he will have served in the second-highest executive branch position in the country for two terms.

With all his experience, it’s only logical that Joe Biden be the Democratic nominee, right?

Well, maybe. Throughout his career, Biden has had a penchant for saying or doing the wrong thing at the wrong time. Jimmy Fallon periodically has a segment where he takes a video of an Obama speech, or some other event, and counts down until Biden does something weird. There was one instance, when Obama’s new Secretary of Defense nominee was being announced; it took him 4 seconds to ruin the moment.

I think Joe Biden will run for president and I think he’ll announce in time for the first Democratic debate. However, I don’t think he’ll get the nomination. With his history for making gaffes at every turn, no amount of political skill could allow him to dig himself out of the rut he would force himself into.

My prediction is this: Biden will run, but Bernie Sanders will get the nomination (unless one of the other lagging candidates makes a surprise leap in the polls); however, with this spread of candidates, I believe it’s going to be a Republican who’ll occupy the White House starting in January 2017.

Biden is expected to announce his bid sometime during the week of Oct. 5.
