No, not an “Assassination Reference”
The Atlantic Wire asks: Did Obama Just Make an Assassination Reference?
The source material that sparked the odd question? The president stating during a fiscal cliff-related press conference: "I’m going to be president for the next four years. I hope."
The piece goes on to ask:
Could he actually have been joking about assassination? About impeachment? The apocalypse? Or has everyone just had enough of these negotiations?
While granting that I do not know what was in the president’s mind at the time, surely the most reasonable interpretation of the remark is simply that the president was acknowledging that the future is not guaranteed. You know, like someone saying “God willing, I will blah blah blah.”
