In January 2016, Jimmy Carter confirmed that he was having regular treatments and said of Rosalynn at the time, "Her support has helped me through the last 69 years since we've been married in everything I've ever tried. Of course, when I was ill and thought I might die at any time, she was there for me." Carter attended the March 11, 2016 funeral of Nancy Reagan at the Ronald Reagan Presidential Library in Simi Valley, California. In July 2016, Carter endorsed Proposition 62, which would abolish the death penalty in California, releasing a joint statement with her husband in support of the measure. She voted for Bernie Sanders in the Democratic presidential primary of that year. Carter differed from her husband in believing Russia had interfered with determining the results of the general election.
