President Obama was born in the U.S. what the birthers are focused on the long form of his birth certificate, they want to create doubt, this same line was used on Bill Clinton when they kept on going after him on Whitewater until something Finally stuck. It is not they really believe he was born in Kenya (don’t you think this would have been found out during the primaries) it is that they don’t like him and will create doubt about him anyway they can, if calling him a socialist works they do that, they had this same game plan for Hillary Clinton the birth certificate is just an added bonus, the conservative GOP movement operates on the principal that everyone else is wrong and they are right, if the stock market goes down it is because of Barack Obama and if it goes up it is in spite of Barack Obama, you cannot have it both ways, either his policies are bad and ruining our economy or if it improves his policies are good and improving our economy, that is not the game these people play, they believe in government for the few and by the few.
John McCain was born to U.S. parents that were stationed in Panama, when you are stationed overseas you are still considered a U.S. citizen and your children are considered born in America,
This is a non issue, if there were legitimate issues to focus on then they should, but not birth certificate conspiracies, they do so at their own peril, the GOP runs the risk of becoming the party of Kooks and Whack Jobs.
the latimes article also contains information on the legality of John McCain's place of birth.

1. US
2. Coco Solo Naval Air Station in the Panama Canal Zone, Panama
3. No

According to his birth certificate and a birth announcement in a local paper the next day, Obama was born in Hawaii. Which is in the USA.

McCain was born on a U.S. military base in Panama. Which counts as sovereign U.S. soil.

No we should not be focused on that kind of crap, but almost by definition conspiracy theorists are very good at wasting time on irrelevent details.
