Born on Earth to middle class parents, Sandra grew to be quite a charismatic teen and the top of her class. Before long, she was attending the planet's top universities with aspirations to become president of the North American Union.
Robinson ran and won in a landslide victory, serving two terms from 2148-2156 CE. She gained useful connections and experience while in office and set her sights on becoming prime minister of the United Nations with the previous PM receiving less than favorable approval ratings.
With an election on the horizon and Robinson already becoming an admirable figure back on Earth, she put her name on the ballot and won in 2166 CE.

Against all the odds, she became both the first woman UN Prime Minister and simultaneously holding a spot on the Assembly. Since then, she has served with mixed results and a high approval rating.
