Senator Kirsten Gillibrand announced her candidacy for President outside the Trump International Hotel. Little known outside of New York, Gillibrand was representing a congressional district in the region around Albany when she appointed, in 2009, to fill Hillary Clinton’s former Senate seat. Gillibrand has been fierce on the issue of sexual assault and harassment, especially in the military and government; as a champion of the #MeToo movement, she was among the first Democrats to call for Senator Al Franken to step down. Some in the Party, she has claimed, are still angry with her over it, and have withheld donating to her campaign. Gillibrand tells David Remnick that her experience as a female politician will be a strength if she were to face Trump in the general election. “My first two opponents were in a 2-to-1 Republican district, who demeaned me, and name-called me, and tried to dismiss me. And not only did it make my candidacy relevant but it got a lot of people deeply offended, and they wanted to know who I was and why I was running.” Trump’s “Achilles’ heel,” she says, “is a mother with young children who’s running on issues that . . . families care about. His kryptonite is a woman who stands up for what she believes in and doesn’t back down.”
