The poem is much more poignant if one imagines that Davis wrote it. Whether he is writing about a young friend, a son, a sexual initiate, or some combination of the three will likely never be known. If Davis named the poem "Pop" for his own literal fatherhood, it is quite possible that Obama himself never knew.
The progressive media do not care to know. And in their world, there is no greater offense than to seek to know something they have chosen not to. Ask Joe McCarthy or Whittaker Chambers or Gary Aldrich or the AGW "denialists" or the Swiftboaters or the CIA interrogators or even poor Linda Tripp. Ask the "birthers."
The literary faithful who have reviewed "Pop" prefer to see in it the seeds of the literary genius that would seemingly blossom in Obama's 1995 memoir, Dreams From My Father. I see in it signs that Obama, even as an adolescent, was willing to take full credit for something he could not himself write.
