TIME editors have nominated Diana Nyad and Edith Windsor to be the magazine's 2013 Person of the Year.

In October, Nyad, 64, became the first person to swim from Cuba to Florida without a shark cage. The openly gay Nyad swam for nearly 54 hours and 110 miles to reach the Florida coast, where she was greeted by dozens of supporters and American and Gay Pride flags.

Windsor is the 84-year-old widow who sued the federal government for not recognizing her marriage to another woman and won. Her Supreme Court case brought an end to the Defense of Marriage Act (DOMA) and led to federal recognition of the marriages of gay couples. The case is also being cited in nearly two dozens cases challenging similar state bans.

Leading in a TIME poll are Turkish Prime Minister Recep Tayyip Erdogan, Egyptian Defense Minister Abdel Fattah el-Sisi and singer Miley Cyrus. The straight yes/no poll will play a factor in determining who will be TIME's 2013 Person of the Year. (Vote for Nyad here; Windsor here.)

TIME's Person of the Year will be announced on December 11.
