I believe the constant “leaks” regarding the Obamas’ lavish travel, parties, and leisure time activities are deliberate finger pokes in the eye of the political right. I mean seriously, how difficult would it be for Obama and crew to restrain themselves while it office, giving the air of austerity, and then live well later? Answer: for a normal family, not much.

Use of office to “live large” at others’ expense is seen as a positive with his base.
