Hillary ClintonHillary Rhodam Clinton will appear on NBC's Saturday Night Live this weekend, the latest attempt to try and humanize the Democratic candidate as the 2016 presidential shifts into high gear.

The schedule appearance will come just a few days after Clinton sat down for a chat with Lena Dunham, which got decidedly mixed reviews from the media. Clinton has also recently appeared on NBC’s “The Tonight Show” with Jimmy Fallon and “The Ellen DeGeneres Show.”

From a communications perspective, trying to personalize Clinton seems like an uphill battle. After all, she’s been in the public eye for nearly 25 years, most recently as U.S. Secretary of State.

If the public still thinks she’s too calculating, the probably might be the candidate herself, as opposed to the narrative that her campaign is trying to create.

When it comes to public figures, Americans love second (and even third) acts. SNL, one of the most enduring TV shows in history, can be a robust marketing vehicle.

Clinton is expected to pop in to join Kate McKinnon, who has portrayed the former first lady as part of the so-called “cold-open” skit, according to the New York Times, citing anonymous sources. (The Clinton campaign has not confirmed the appearance, said several reports.)

Clinton, of course, is no stranger to SNL. When she was a U.S. Senator, she appeared on the program in 2008 to poke fun at her own laugh (or guffaw).

Watch for Clinton to make other attempts at self-deprecating humor when she appears on SNL this weekend.

The electorate, of course, gravitates toward candidates who can laugh at themselves and display warmth and likeability. Should Clinton hit it out of the park this weekend, her candidacy will probably benefit from a slight surge.

On the other hand, people have very short memories, and Clinton’s appearance—even if it’s boffo—will probably be quickly forgotten. Until the next one, that is, which we won’t rule out.

If Clinton makes a major gaffe while appearing on SNL, look for it show up in a GOP attack ad during the general election.

Ah, the nexus between politics and showbiz.
