JOHNS CREEK, Georgia — How does an Indian American candidate for state Senate campaign in Georgia these days? In the case of Ashwin Ramaswami, he visits a local cafe known for its red bean buns and matcha lattes and discusses his views with a group of Korean American mothers.

Ramaswami is a 24-year-old Stanford University graduate who gave up a government cybersecurity job to run as a Democrat in Georgia’s 48th Senate District, an area that includes a large swath of Atlanta’s northern suburbs and is 28.3% Asian American, according to the Atlanta Regional Commission.
