Obama tells audiences how his parents met and conceived him:

What happened in Selma, Alabama and Birmingham also stirred the conscience of the nation. It worried folks in the White House who said, “You know, we’re battling Communism. How are we going to win hearts and minds all across the world? If right here in our own country, John, we’re not observing the ideals set fort in our Constitution, we might be accused of being hypocrites.” So the Kennedy’s decided we’re going to do an air lift. We’re going to go to Africa and start bringing young Africans over to this country and give them scholarships to study so they can learn what a wonderful country America is.

This young man named Barack Obama got one of those tickets and came over to this country. He met this woman whose great great-great-great-grandfather had owned slaves; but she had a good idea there was some craziness going on because they looked at each other and they decided that we know that the world as it has been it might not be possible for us to get together and have a child. There was something stirring across the country because of what happened in Selma, Alabama, because some folks are willing to march across a bridge. So they got together and Barack Obama Jr. was born. So don’t tell me I don’t have a claim on Selma, Alabama. Don’t tell me I’m not coming home to Selma, Alabama.

The first march on Selma took place on March 7, 1965 (there were three of them). At the time, Barack Obama was three and a half years old. Now, Obama also mentions the Birmingham march as part of this speech — but that took place in May 1963. Obama would have been 20 months old when Dr. King led that demonstration.

That’s not the only bit of fabulism here. Obama’s birthdate is August 4, 1961. It doesn’t take a doctor or a math whiz to calculate his conception as sometime in 1960 — before John Kennedy took office. In fact, it might have taken place on Election Day, when Kennedy won the presidency. That would tend to indicate that Mom and Dad met sometime before the African airlift that Obama credits for his birth.
