Senator Claire McCaskill of Missouri has been ahead of the game when it comes to backing presidential candidates. She supported both Barack Obama (2008) and Hillary Clinton (2016) and was one of the first to endorse each candidate. McCaskill is currently serving a second term as a Senator for Missouri, defeating Todd Akin after his infamous “legitimate rape” comments. She has already announced that she’ll be seeking a third term in 2018. However, Missouri is a very red state and there’s a slight chance that McCaskill won’t hang on to her Senate seat. This would leave her with an opportunity to run for President instead.

During her time in Congress, McCaskill has served on committees for homeland security, armed services, aging, and commerce, science, and transportation. She has been a strong supporter of women in business, joining Facebook COO Sheryl Sandberg’s “lean in” movement. McCaskill has also taken up the fight against sexual assault in the military and on college campuses as well as waste and fraud in government contracts. In February of 2016, she disclosed that she had received a breast cancer diagnosis, adding that her prognosis was good and she was expecting a full recovery, presumably well before the 2020 race.
