Colbert reveals Bernie Sanders' new campaign song

It's hard for a candidate to preach against the thing that he's become.

But in many ways that's the position that Democratic front-runner Bernie Sanders (he's now surpassed the lead that potential candidate and former Vice President Joe Biden had) finds himself in. His tirade against the wealthy has less punch now that his tax returns (he recently released 10 years' worth) reveal that he's one of them.

His best-selling book has made him a millionaire, and his solution for everyone else is to write a best-selling book, too. Well, why didn't the 99% think of that?

But don't worry, if you're among the non-wealthy, Sanders has written another book that might help. Late-night comic Stephen Colbert introduces the candidate's newly penned tome on tips for getting wealthy through socialism. And what's Sanders' new campaign song? Take a look at today's Best of Late Night, above, to find out. Hint: This one has nothing to do with the 99%.

But rising poll numbers aren't Sanders' only win. He had a few highlights during his recent town hall meeting on Fox News. However, the format also revealed something else. Comic Jimmy Fallon will fill you in on how the candidate's age was showing.
