Joe Biden's book "Promises to Keep" (Courtesy/Courtesy)

To paraphrase Mel Brooks, it’s good to be president. Really good.

Vice president? Well, not so much — at least when it comes to selling books.

Browsing through President Obama’s and Vice President Biden’s financial disclosure forms, we noticed that Biden checked the “less than $201” box on his income from Random House for his 2007 memoir, ”Promises to Keep.” (It’s actually a very fine book.)

Obama, meanwhile, checked the box “$100,000 to $1 million” for royalties last year on “Dreams from My Father,” first published in 1995 when he was running for state office, and “$50,000 to $100,000” last year for “The Audacity of Hope,” published in 2006 when he was a senator.

(A 2010 book, “Of Thee I Sing: A Letter to My Daughters,” netted between $100,000 and $1 million, but the proceeds go to the Fisher House Foundation.)
