He also served five terms in the National Assembly and led the conservative Grand National Party in 2011, as well as its successor, the Liberty Korea Party, from 2017 to 2018.
He was the presidential nominee of the Liberty Korea Party in the 2017 South Korean presidential election and came in second place during the general election, losing to Moon Jae-in. Hong ran as a candidate in the 2022 South Korean presidential election for the nomination of the conservative People Power Party and came in second place during the primaries, narrowly losing to Yoon Suk Yeol. Hong was elected Mayor of Daegu in 2022, but he resigned to launch his third campaign for the presidency in the 2025 South Korean presidential election. Although he advanced from the first round, Hong ultimately failed to win the party primary, subsequently announcing his retirement from politics.
