How come Obama wont' release his Certificate of Live Birth?

1994 The Immigration and Nationality Technical Corrections Act of 1994 amended several sections of the Immigration and Nationality Act, and took effect on March 1, 1995.

Amended Section 322 permits children born overseas of a U.S. citizen parent to be eligible for a certificate of citizenship if either their U.S. citizen parent or a U.S. citizen grandparent had been physically present in the United States for at least five years, two of which after the age of 14, prior to the child's birth abroad. This provision also applies to a child adopted abroad.

Amended Section 301 (h) gives back U.S. citizenship to a person born before noon (Eastern Standard Time) May 24, 1934, outside the limits and jurisdiction of the United States of an alien father and a mother who is a citizen of the United States who, prior to the birth of such person, had resided in the United States.

Amended Section 324 (d) (1) allows former U.S. citizens who lost their citizenship through failure to meet the former conditions of physical presence in the United States to retain their citizenship to regain their citizenship without having to file an application for naturalization.

The law also allows U.S. citizen parents to apply for U.S. citizenship from abroad for their foreign-born children under the age of 18, provided the child is physically present in the United States pursuant to a lawful admission when the citizenship is granted.

No person except a natural born citizen, or a citizen of the United States, at the time of the adoption of this Constitution, shall be eligible to the office of President; neither shall any person be eligible to that office who shall not have attained to the age of thirty five years, and been fourteen Years a resident within the United States.
