The Washington Post notes that Sarah Palin's second book is nowhere near the blockbuster that her first book was:

"America by Heart," Palin's new memoir, has logged disappointing receipts since it officially went on sale late last month, publishing sources say. Although the book is second on the New York Times bestseller list this week (behind former president George W. Bush's memoir, "Decision Points"), its publisher, HarperCollins, hasn't ordered a second printing - a sign that sales haven't been overly brisk.

Her reality show keeps hitting new lows, too. Now, book sales and TV ratings don't correlate with political clout, but a good publicity machine can manage to keep buzz going for the long haul; the Palin brand doesn't seem to be very good at endurance.
