With the development of Macau’s democracy, and the increasing number of the deputies to the Legislative Assembly elected directly by Macau residents, the competition in the direct election of the Legislative Assembly has become increasingly fierce. As an association with objectives of patriotism, concerning the interests of the grassroots and paying close attention to the needs of the livelihood of the people, the experience of the People’s Alliance for the Construction of Macau participating in the past three direct elections of the Legislative Assembly may have some implications for us to analyse the basis to gain support and trust among voters by associations and their candidates.
