Sanders' campaign adventure takes him from Hamilton to Rome

In the past few months the Vermont senator and his wife, Jane, have traveled to Rome to attend a conference and met Pope Francis, toured Mount Rushmore and rallied supporters in sunny Puerto Rico.

Earlier this week, he dropped in on the final game of the NBA's Western Conference finals.

Sanders' his freewheeling political adventure could soon end as former Secretary of State Hillary Clinton approaches the magic number needed to clinch the Democratic nomination and calls intensify for Sanders to exit the race.

[...] while former President Bill Clinton famously played his saxophone alongside late night show host Arsenio Hall and President Barack Obama would play basketball on the day of primaries and faithfully completed his NCAA tournament bracket as president, few candidates have taken as many side excursions as Sanders.

In the final weeks of his failed 2012 primary bid, animal lover Newt Gingrich spent a lot of time visiting zoos — trips that resulted in many photos of the candidates with a variety of animals.

Puerto Rico is a voting territory, Pope Francis is a world leader and events and shows provide access to supporters and new opportunities to push his message.

After enthusiastically taking in a Golden State Warriors' victory, Sanders called the team's comeback win "a very good omen for our campaign," according to CNN.

Presumptive Republican front-runner Donald Trump has not done as many side activities, though he has used his campaign to promote his products, including a Trump hotel under construction in Washington and a newly renovated golf course in Scotland, which he will visit later this month.
