Al Franken has to be the most influential politician in America right now. Not because he’s fighting the good fight and keeping them honest and all that, but rather because the President must ascribe to Stuart Smalley’s Daily Affirmations. I mean, how else could Donald Trump get through a single day of talk about impeachment and “the beginning of the end” without looking in the mirror and saying, “You’re good enough, you’re smart enough, and doggone it, people like you.”

Aside from being a Minnesota senator, Franken is also the author of Lies and the Lying Liars Who Tell Them — a title that seems especially prescient these days. Now he’s out with a new book, Al Franken, Giant of the Senate, a memoir about his unlikely political career that also promises to delve into “our deeply polarized, frequently depressing, occasionally inspiring political culture.”

On May 31, a day after the book’s publication date, Franken will be holding forth at Barnes & Noble Union Square. Don’t worry, the Senate isn’t in session that day, so this won’t distract him from “systematically destroying” Trump’s talking points on the Comey firing, or fighting against the GOP’s “terrible” new healthcare plan.

It’s uncertain whether there’ll be a Q&A session. If there is, don’t bother asking him if he’s planning to run for president in 2020, because he’s already answered that.

By the way, just because Franken is an “honorable gentleman” now, doesn’t mean he has lost his sense of humor. Here’s an excerpt of him reading from the book.
