And we had 30 other countries that at one time have had a female president.

Now if you include other categories such as honorary president, you then expand the size of this larger group past 30. For example China had a female honorary president in 1981. Now Song Qingling was the female president in 1981 of China, but before that China has had several different constitutions since it went communist, during the 70s there was no position as president and the head of state during some of those years was the person who was in charge of the congress and Song Qingling was Chairman or should we say Chairwoman of the Standing Committee of the National People's Congress from 1976 to 1978.

That said the first time a female president and not something else like honorary president, chairwoman, prime minister, etc was Argentina in 1974.

At least I assume all of this wikipedia information is true

Sigh I hope we get a great president soon, and I will have no problems if she is Female and it would be great to have more women serve in public office.
