Circumstantial. From memory, her aunt Eleanor (Stanley Dunham's sister) lived in Blaine Washington, which is right across the border from Vancouver. It was not uncommon for people to send girls with embarrassing pregnancies to go live with relatives.
Barack Obama Sr had written a letter declaring that it was the intention of he and Stanley Ann to give the baby up for adoption.
Records indicate that Stanley Ann Dunham was in Seattle on August 19th, which is too soon to fly after an August 5th birth. Airlines wouldn't allow such young infants on flights in that era.
Hawaii also allows people to obtain birth certificates even if they are not actually born in Hawaii, so long as Hawaii is the parent's residence.
There are a few other bits and pieces, but it makes a good circumstantial case that Obama was born in Canada.
What records? The internet says she started classes 15 day after BHO was born. It also tells us that Fall term didn't start until September 25th, over a month and a half after he was born. I assume Summer classes didn't start in mid-August.
Hawaii also allows people to obtain birth certificates even if they are not actually born in Hawaii, so long as Hawaii is the parent's residence.
But was that still in effect when Obama was born?
Do you find it at all odd that not one investigator has ever produced evidence of this? To my knowledge, not one writer, not one sleuth, no one, has ever produced evidence that Obama was born in Canada. Strange, isn't it?
