His stance against Trump and refusal to support Republican candidates, including Herschel Walker, further alienated him from the party.

The party's Executive Committee made this decision based on Duncan's opposition to GOP candidates, his potential third-party presidential bid, and his backing of Democratic campaigns.

Duncan, who served as lieutenant governor from 2019 to 2023, often clashed with party members and publicly criticized GOP candidate Herschel Walker's Senate bid in 2022.

After losing the primary to Trump-backed David Perdue in 2022, Duncan chose not to run for re-election and pledged to support Democrats against Trump in the upcoming 2024 elections.

As of now, the Georgia GOP has not issued any further comments regarding Duncan's expulsion.

Duncan's actions and statements have been interpreted as direct opposition to Trump's campaign for a second term.

The resolution passed against Duncan prohibits him from using his Republican affiliation and bans him from all GOP properties and events.

Before his tenure as lieutenant governor, Duncan served three terms in the Georgia House of Representatives, where he was once considered a rising star in the GOP.

Duncan also declined to endorse Burt Jones, the Republican nominee to succeed him as lieutenant governor, due to Jones's support for Trump.

The Georgia Republican Party has expelled former Lieutenant Governor Geoff Duncan, citing disloyalty due to his support for Kamala Harris during her campaign.

In a May 2024 article, Duncan endorsed Biden, arguing that Trump had disqualified himself due to his actions related to the January 6 Capitol riots.

In response to his expulsion, Duncan criticized the resolution on social media, suggesting the party should focus on more pressing issues instead.
