It’s partly to get out of town while all the damaging info is coming out, partly to shore up his weakening support among blacks, and partly just to say a big FU to the US.
I actually do think he’s shopping around for a country to take over as his African base. I read that AQ is becoming more of a problem in South Africa but that since 2010 the police there have been forbidden to conduct any surveillance of suspected AQ facilities or even known members. So maybe he’s prepping for the next stage of his demonic life.
Plus, think of the media coverage and photo ops as they compete to have the most footage of the first family in Africa. I can hear Diane Sawyer commenting on something about the first daughters, multiple scenes of POTUS and FLOTUS getting on and off airplanes, shaking hands... kind of like a campaign tour. There will be precious little time for the MSM to talk about the IRS, State Dept, Benghazi, etc.
