Over the course of the Obama presidency, particularly during the second term, Michelle Obama was subject to speculation over whether she would run for the presidency herself, similarly to predecessor Hillary Clinton. A May 2015 Rasmussen poll found Obama had 22% of support to Clinton's 56% of winning the Democratic nomination, higher than that of potential candidates Elizabeth Warren, Martin O'Malley and Bernie Sanders. Another poll from that month found 71% of Americans believed that Obama should not run for the presidency, only 14% approving. On January 14, 2016, during a town-hall meeting, President Obama was asked if the first lady could be talked into running. He responded, "There are three things that are certain in life: death, taxes, and Michelle is not running for president. That I can tell you." On March 16, 2016, while speaking in Austin, Texas, Obama denied that she would ever run for the office, citing a desire to "impact as many people as possible in an unbiased way". In the epilogue to "Becoming", Obama writes, "I have no intention of running for office, ever," recognizing that "politics can be a means for positive change, but this arena is just not for me."
