This morning, Senator Joe Biden visited Today with his memoir Promises to Keep: On Life and Politics (Random House, $25.95), which pubs today. Tonight, he’ll be on the Late Show with Dave Letterman and tomorrow on The Early Show.

On The Brian Lehrer Show, Steve Ettlinger unwrapped Twinkie, Deconstructed: My Journey to Discover How the Ingredients Found in Processed Foods Are Grown, Mined (Yes, Mined), and Manipulated into What America Eats (Hudson Street Press, $23.95; Listen & Live Audio abridged CD, $29.95). PW found it a “delightful romp through the food processing industry.”

Authors on The Leonard Lopate Show:

Professors David Weiman and Michael Stoll, co-editors of Barriers to Reentry? The Labor Market for Released Prisoners in Post-industrial America (Russell Sage Foundation Publications, $37.50).

Carol Muske-Dukes with her fourth novel, Channeling Mark Twain (Random House, $24.95). PW’s review had this to say: “Fiction with a political conscience often sacrifices craft in favor of driving home a message, but Muske-Dukes pulls it off.”

The Diane Rehm Show hosted Tony Blair’s former press secretary Alastair Campbell, author of The Blair Years: The Alastair Campbell Diaries (Knopf, $35).

On PRI’s The World: former diplomat Michael Hamilton Morgan, author of Lost History: the Enduring Legacy of Muslim Scientists, Thinkers and Artists (National Geographic Books, $26).

This evening, The Colbert Report meets with two-term Maryland lieutenant governor Kathleen Kennedy Townsend, author of Failing America's Faithful: How Today's Churches Are Mixing God With Politics And Losing Their Way (Grand Central Publishing, $24.99).

Tavis Smiley re-airs an interview with Sherman Alexie, author of Flight (Grove/Black Cat, $13), his first novel in 10 years, which PW’s review said “elegantly mixes free-floating young adult cynicism with a charged, idiosyncratic view of American history. Alexie plunges the book into bracing depths.”
