Some of the best politicians in the world have been female. Cristina Fernández de Kirchner in particular is the current and 55th President of Argentina. This should not be considered unusual by anyone, as women politicians have been around forever, whether they were formally identified as holding a political position or not.
Case in point, Susan B. Anthony was an American civil rights leader who eventually made it possible for women to vote in the 19th century. This, in itself, changed who was getting elected into public offices throughout the globe and the 20th century. Many female politicians were highly controversial playing around with tarot card readings, while others were political candidates out of compromise. There have been several female politicians who followed their husbands or fathers into publicly held offices, while other women were appointed or elected based on their own merit and political contributions.
More recent woman politicians, some of which you will likely be familiar with: Margaret Thatcher, Great Britain’s Prime Minister from 1979-1990, Violeta Barrios de Chamorro, Nicaragua President from 1990-1996, Helen Clark, New Zealand Prime Minister from 1999-2008, and Golda Meir, Israel Prime Minister from 1969-1974, just to name a handful.
