Crafting the perfect political slogan is hard. Writing scores of unmemorable ones? Less so.

Buried in the leaked emails of Hillary Clinton’s campaign chairman, John D. Podesta, is a message from August 2015, when the campaign was weighing a list of prospective slogans for Mrs. Clinton’s candidacy. Some ring familiar:

■Progress for the rest of us. Not quite a “Festivus for the rest of us,” in “Seinfeld” parlance, but in the ballpark.

■Building a better tomorrow. Does not appear to have the blessing of Stephen Colbert’s former “super PAC” — “Americans for a Better Tomorrow, Tomorrow.”

■Go further. A rallying cry on which a Ford branding effort was once premised.

■Renewing our basic bargain. Calls to mind the stay-the-course-but-not-entirely ethos of Selina Meyer on “Veep.” (Her slogan: “Continuity with change.”)

Then there is the final section of the email, under the themed heading “It’s about you,” which — taken as a whole — reads as its own sort of inspirational pop-song stanza.
