After his death, she went to night school to do post-graduate studies in marketing management and began her professional life in the field of graphic arts. Her husband had been a PSD councillor for the municipality of Rio Maior and in 2001 she also decided to join the party and was elected president of the Rio Maior parish council. In 2009, she was elected president of the Rio Maior municipality with 49.21% of the votes, the first defeat for the Portuguese Socialist Party in Rio Maior for 24 years. She held this post until 2019.[4][5]
In 2019 she was invited to head the PSD list for the Santarém constituency in the national election. She accepted as, after three terms, it would not have been possible for her to stay on the municipal council, and was duly elected to the Assembly of the Republic. In Parliament, she chaired the parliamentary committee on Public Administration, Administrative Modernization, Decentralization and Local Power. She also served as a vice-president of the National Political Commission of the PSD. In the 2022 election she was again first on the PSD list, with the party winning three of the nine seats available in the constituency. In 2024 she was re-elected as the third-choice candidate of the Democratic Alliance.[1][2][6][7]
After being chosen in March 2013 to be part of the Portuguese Sports Foundation's executive committee for the management of high-performance centres, to represent municipalities with such centres, in December of the same year Morais was appointed to be a member of the National Sports Council (Conselho Nacional do Desporto), joining famous Portuguese sports people such as the Olympic marathon winners, Carlos Lopes and Rosa Mota, and the racing driver, Pedro Couceiro. Her appointment was seen as a recognition of her contribution to the achievements of Rio Maior in promoting sports and supporting national sporting teams.[8][9]
