Since I never heard of Adele and voted for George Bush, my vote's on George Bush.
Seriously, this question is better suited for a poll rather than a question-and-answer database (IMHO).

George Bush.
Presidents and singers run in different circles so their fame in not really comparable. However at this present time, Jan. 2013, Bush has stepped out of the limelight and keeps a low profile whereas Adele is probably at the height of her career, so she is can probably claim to be more famous at the moment. In a hundred years, Adele will be totally unknown except to a few pop culture experts but Bush will still be mentioned in American history classes throughout the country.
