2021 parliamentary selection effort
In 2021, the Australian Financial Review (AFR) reported that Campbell who had been considered a potential Senate preselection candidate instead sought preselection for the Division of Casey in the 2022 federal election. The AFR reported that journalist and former Liberal staffer James Campbell, the husband of the candidate, supported her pre-selection and became the primary carer of their children during the preselection period.[9]
Had Campbell won, she would have made history as the first woman of Indian descent to serve as a Liberal member of parliament.[13] Campbell ultimately lost the by-election to Mary Doyle, the candidate of the Labor Party.[14] During her concession speech, Campbell stated that "I will always be proud to be a Liberal and I will always be proud to be Australian because we live in the greatest country in the world."[15]
