Vermont Sen. Bernie Sanders will become the latest presidential hopeful to guest on NBC’s The Tonight Show Starring Jimmy Fallon on Tuesday, December 8. It will be Sanders’ first to the show that’s already made headlines hosting Dem front-runner Hillary Clinton and GOP front-runner Donald Trump.

News of the booking comes as a new Quinnipiac University national poll shows Clinton widening her lead over Sanders to 60%-30%, compared with 53%-35% last month. Place your bets now, in re if and how NBC’s late-night Sanders doppelganger Larry David shows up on the candidate’s late-night appearance with Fallon.

Sanders has been good for late-night TV shows. ABC’s Jimmy Kimmel Live clocked the biggest night of its Brooklyn week in October, when Sanders joined Michael J. Fox to participate in the show’s Back to the Future Day celebration, being booked right after Trump canceled on Kimmel at the eleventh-hour citing a “political commitment.” A very enthusiastic Brooklyn audience lapped up Sanders’ talk about pot and free college tuition. During his visit, Sanders impersonated David impersonating Sanders. The result: Kimmel’s highest-rated Wednesday in nearly two years.

In September, Sanders made big headlines on The Late Show with Stephen Colbert by saying, “What Trump is doing is appealing to the baser instincts among us — xenophobia and, frankly, racism. You target some group of people, you go after them. You take people’s anger and you turn it against them. You win votes on that. I think that is disgraceful and not something we should be doing in 2015.”

And, of course, Sanders is responsible for the zippiest line of a Dem debate to date when he declared America sick and tired of Hillary Clinton’s emails.
