Even if a presidential run isn't really a promising option for Biden, he should have many other opportunities come 2017.

Or he might pursue options on corporate boards, in academia or in the media and publishing.

Still, if Biden wishes to continue to serve in public office, there are at least four major political paths forward for him in 2016:

Governor: At first glance, Biden's most obvious opportunity for elected executive office is in his own home state of Delaware. The incumbent Democratic governor is term-limited and cannot run again in 2016. Over in California, 76-year-old Jerry Brown is demonstrating, in his second stint as governor, that political veterans can bring innovative ideas and tackle new challenges.

However, tiny Delaware offers a much smaller stage than the Golden State, perhaps too small for a former vice president. More importantly, Delaware already has a potential Gov. Biden in its near future: Beau Biden, the state's attorney general and the vice president's son, who has indicated his intention to run for governor in 2016. So while Joe Biden will likely be on the campaign trail in Delaware, it won't be as a candidate.

Senator: Biden is truly a "man of the Senate," having spent more than half of his there, as a senator from 1973 to 2009 and as Senate president since his election as vice president. And it wouldn't be unprecedented for a vice president to return to Congress, as five went on to serve in the Senate. However, Delaware already has two Democratic U.S. senators and, in any case, neither seat is up for reelection in 2016.

But next door in Pennsylvania, Republican Sen.

Biden is a native son of Scranton, Pa. and lived much of his life in Wilmington, Del., which is a stone's throw from Pennsylvania and more or less part of greater Philadelphia. He'd thus be largely immune to charges of carpetbagging, and could help consolidate the Democrats' bid to retake the Senate in 2016.

Cabinet official: In the run-up to the 2012 election, one commonly cited scenario was that Biden and Clinton might switch positions. As long-time chair of the Senate Foreign Relations Committee and as a former vice president, Biden would make a formidable secretary of state. However, President Obama had unique reasons for installing a "rival" in the powerful position of secretary of state. Having served in that role herself, Clinton might be all the more likely to want to maintain greater control over that portfolio. That said, Biden could be a plausible candidate for many other Cabinet-level jobs, including top positions such as attorney general or secretary of Defense.

It might be noted that the only modern example of a former vice president joining the Cabinet, Henry Wallace as secretary of Commerce in the 1940s, did not end well — he clashed with, and ultimately ran against, his boss, President Truman. But Biden and Clinton are said to have excellent personal and professional rapport.

Ambassador: Representing the U.S. to a major foreign power is yet another route forward for a former vice president. The most obvious choice would be Japan, where the government highly prizes an ambassador with name recognition and well-established access to the Oval Office. Caroline Kennedy is now in that role; during the 1990s, it was filled by former Vice President Walter Mondale.

At a time of heightening international tensions in East Asia and beyond, a veteran of Biden's stature could be a huge asset in Japan, but also in another major power such as China or Russia. A former vice president can also be a potent special envoy, navigating difficult shoals such as, for instance, reestablishing diplomatic relations with Iran.

Joe Biden has been a Democratic Party stalwart, a national leader and a prominent statesman since the 1970s. Still, not every Oscar nominee can win the Best Actor award, nor can even the most talented athlete always become the MVP. The presidential hopes of the Democratic Party are focused elsewhere for 2016. But that doesn't mean Biden couldn't still have an important role to play on the team.
