With just weeks to go before the Philippines holds a presidential election, the lone female candidate is attracting some of the biggest pre-election crowds in decades as she seeks to pull a stunning upset against front-runner Ferdinand Marcos Jr.

Leni Robredo, who became vice president in 2016 after defeating Marcos Jr., has dispersed more than two million volunteers to go house-to-house and visit local markets to speak about her accomplishments and counter disinformation on social media that her campaign says comes from her opponents.

The question is whether the groundswell of support for Robredo is too little, too late: A poll in March found the 57-year-old lawyer was trailing by more than 30 percentage points to Marcos Jr., the only son of the late Philippine dictator Ferdinand Marcos.
