A potential first female US president would be a political milestone not just for America but for other democracies like Australia, advocates say, ahead of Kamala Harris' likely endorsement as candidate in the upcoming election.
President Joe Biden announced he would not seek re-election after mounting pressure to drop out and endorsed Ms Harris as his successor to run against Donald Trump in the presidential election on November 5.
While Ms Harris would have to be formally nominated at the Democratic Party's national convention in August, chief executive of Women for Election Australia Licia Heath said the move would be "significant" for women in politics around the world.
