Dennett returned to lobbying Congress in 1922, pointing out that private opinion of members of congress must be in favor of birth control since the average number of children of a member of congress was 2.7. She continued to have difficulty finding sponsors for the bill, but in 1923 finally succeeded, when Senator Albert B. Cummins introduced the straight repeal bill in the Senate. However, the bill made no further progress during that session, since Cummins was unable to succeed in getting the rest of the Senate to vote on it due to mass absenteeism when it came up for a vote.
