A deadpan text outlines a president’s extensive duties, while Madam—a ponytailed girl in a snappy pin-striped pantsuit—trips through an exhausting day, bestowing small American flags as she goes. Smith’s illustrations combine cartoonish figures, mod interiors and stylized landscapes a-swirl with fall leaves. A whimsical double-page spread proclaiming “A president must choose a capable cabinet” pairs toys with their official titles: Mr. Potato Head is Secretary of Agriculture, for instance, and a winged unicorn is “Secretary of Fantasy.” Such retro elements as a deck of Old Maid cards and a Ruth Buzzi button will tickle adults, as might a Duck Soup–derived reference to “[t]he ambassador of Freedonia.” Children can squint at the spines of Madam Prez’s library (which leans to American history) and spot scores of visuals signaling her obsession (presidential busts, a pet cat doubling as a Secret Service agent). Though the Oval Office here is no more than a messy bedroom, this funny romp lightly delivers a hefty message for today’s girls: The White House is yours for the taking. (Picture book. 4-8)
