At 28, Jeff Shesol lacks the name recognition of fellow generationalists Brad Pitt or Kurt Cobain. But have they authored a 591-page doorstop on the festering relationship between Lyndon B. Johnson and Robert F. Kennedy? Have they drawn a nationally syndicated comic strip called Thatch? And have they unleashed upon the world a genie as sinister as political correctness, which the liberal-to-moderate Shesol inadvertently loosed while a Brown undergrad? I should think not. Shesol’s far-flung handiwork is enough to make even the slackest Gen Xer envious—though twentysomethings can rest assured that neither Hollywood nor television has presented him with megabucks yet. Still, Shesol has lots of time before he turns 30. Hear the shockingly unassuming Shesol discuss his LBJ-RFK book, Mutual Contempt, at 7 p.m. at Politics & Prose, 5015 Connecticut Ave. NW. FREE. (202) 364-1919. (Louis Jacobson)
