On October 20, 1913, Florence's father passed away. Despite their strained relationship, his daughter received $35,000 and valuable real estate in the will. Florence had her own health problems, suffering a serious kidney attack in the winter of 1913 and went to live at the White Oaks Sanitarium. Dr. Sawyer feared that Florence would not survive the year, but his patient managed to recover. In spite of her ill health, she encouraged her husband to run for Senate in 1914 and resolved to be part of the campaign. She limited her role to advisory management and persuaded her husband to ignore pressures to have anti-Catholic remarks against the Democratic opponent, Timothy Hogan. With her assistance, Warren won the Senate election by 102,000 votes.
