I'll add, not much forging went on here because THIS IS VIRGINIA SUNAHARA'S BIRTH CERTFICATE. Ann Dunham hijacked her certificate to use for her son. Barack's birthday was changed to Aug. 4th BECAUSE VIRGINIA'S BIRTH DAY WAS AUG. 4TH. Aug. 4th is NOT Barack's REAL birth date.
Remember when, on July 15th he said "I'll be turning 50 in a week"? That would make his birthday AT THE END OF JULY, not Aug. 4th.
Also, note that the 'R' in BARACK is different than the other letters. THIS IS BECAUSE THE 'R' IN 'VIRGINIA' WAS RETAINED TO KEEP THE CHARACTER SPACING CORRECT FOR 'BARACK'. Trivial but interesting.
