Well, Mombasa can't be on the way to Obama Sr.'s village from Nairobi if it's 450 miles from Nairobi in the exact opposite direction.
So given that Mombasa is around 900 miles from Obama Sr.'s village, is not on the way from Nairobi, and Nairobi is the only pluasible city through which a pregnant Stanley Anne would have entered the country had she visited it in 1961, what on earth makes you suspect Obama Jr. was born in Mombasa?
I understand why you suspect he was born in Kenya. As a factual proposition, it's absurd, or course. However, if one analyzes birthism as a religion, it makes sense for you bithers to designate Kenya as Obama's birth country in your belief system, given that it is his father's country of origin.
But Mombasa? Why Mombasa? A city on the other end of the country with which no one in Obama's family had any connection? A city which Obama's mother would have had no reason to visit, even if she took that mythical pre-natal trip to Kenya in which birthers so fervently believe?
It doesn't make any sense at all, even taking into account the religious nature of birthism.
Misdirection ... Mobassa is close to a sea port. Airport use was probelmatic.
