I believe that a woman could or should be president will not make a difference. Man or Woman president will be guided by the same law and abide to the same procedures in running the country. There will be conflicts in opinions because women have different perspective than men. Besides, it is too early to tell since America has not experience having a woman president yet. But, it's just because there has never been a woman president in America doesn't mean there can't be one.
In my opinion, when a woman becomes a president especially in America there will be lots of changes and amendments on the policies especially those involving family, women and children's issues. It will inoculate a signal to the whole country that anybody can be president regardless of race and gender.
