Obama: In a few years your two daughters will be out on their own.
Out of curiosity, they may decide to submit to DNA tests just to prove once and for all that your father came from Kenya, and there is nothing legally you can do to stop them.
For instance, I think Ancestry has a quick and cheap test that your two daughters can take advantage of.
There are also tv shows that trace the background of entertainment stars, and I believe the shows rely heavily on DNA tests.
Yes, you might want to go on one of those DNA tv shows---I think one of them is hosted by your professor friend at Harvard---BEFORE you go to Kenya in July, because if the DNA tests show that your father did NOT come from Kenya, it might save you from going on such an embarrassing trip to Kenya.
Obama’s DNA stands for Don’t Know A Lot.
