呢次初選得到民主派主要政黨同埋唔少新興組織，好似公民黨、人民力量、民主黨、社會民主連線，天水連線、屯門社區網絡，醫管局員工陣線、專業議政，仲有部份無黨籍民主派、本土派人士同埋政治素人參與。不過，城邦派政黨熱血公民，就批評選舉唔符合民主基本意思。選舉亦受到香港官員批評，指初選違反《中華人民共和國香港特別行政區維護國家安全法》。
The primary election was attended by major pro-democracy parties and a number of emerging organisations, such as the Civic Party, People Power, Democratic Party, Social Democratic Union, Tin Shui Link, Tuen Mun Community Network, Hospital Authority Staff Front, Professional Politics, as well as some independent, localist and political amateurs. However, the city-state party has criticized the election for not being in line with the basic meaning of democracy. The election was also criticized by Hong Kong officials for violating the People's Republic of China Hong Kong S.A.R. National Security Law.
