A Broadway musical produced by former Secretary of State Hillary Clinton is having trouble filling seats during its key season.

“Suffs” is a musical about the 1913 suffragettes ahead of the 19th Amendment to the Constitution. With about a month until the Tony Awards, “Suffs” reported an attendance of 81% the week ending on May 5, which was a slight increase from the week before. However, its gross revenue remained largely the same at just over $630,000 each week according to the Broadway League, a trade website for the theater industry.
