Obama's years in office would immediately take on the soft, gauzy feel of a latter day Camelot. He would be forever frozen in time forever as a relatively youthful icon. One can only imagine the purple prose that would be summoned up for his various eulogies. Liberals would compete to outdo each other in their fulsome praise for him (thereby proving what good people they are).
Obama would be said to have "given his life" for the cause of bringing much needed medical attention to poor people. He would have practically died for our sins.
Pictures of Obama's grieving family (well, the official photographer's ones, anyway, the regular new agencies will probably continue to be denied access) would saturate the airwaves. They would be shown over and over, much like the shot of John-John saluting his father's coffin or the one of a tear-stained Jackie standing next to LBJ when he took the oath of office.
Even if Obama were to be killed by someone with no connection to conservatism, that killer would most likely be instantly Jared Loughner-ized: given right wing credentials he didn't have. Or, as also happened with Loughner, the killer would merely be said to have been emboldened by the atmosphere of hatred promulgated by the right wing.
Let's hope Obama leads a long life, allowing the public to see his character in full. His lavish personal lifestyle. His soaring oratory, when he has no Teleprompter. And his sexual inclinations, once the media has less incentive to ignore them.
All of these things can only be revealed in the fullness of time; so please join me in wishing Barack Obama a long, illuminative life.
