Ashwin Ramaswami, a Democrat running for a Georgia State Senate seat, grew up in a wealthy stretch of Atlanta suburbs transformed by the tech industry and waves of Indian American immigrants, like his parents, who have settled there.

It is a part of the American South where the percentage of adults with a bachelor’s degree is significantly higher than the national average. Mr. Ramaswami, 25, fits right in, with a computer science degree from Stanford and a law degree from Georgetown.

He was still in law school when he realized that the state senator for his hometown, Johns Creek, was among the 18 people indicted last year with former President Donald J. Trump on charges that they had illegally interfered with the 2020 election results in Georgia.

That is when Mr. Ramaswami decided to run for office.

Today, his audacious Gen-Z challenge to the Republican incumbent, Shawn Still, a 52-year-old swimming pool contractor, may prove to be a long shot in Senate District 48, which was drawn to tilt Republican. But it will serve as a test of Democrats’ argument that anyone who helped try to change the 2020 election result is unfit for office.

The race will also test the strength, and political proclivities, of the growing Indian American community in the populous suburbs north of Atlanta.

In recent weeks, Mr. Ramaswami has been traveling from subdivision to subdivision, knocking on doors and making his case that Mr. Still should not remain in government. Mr. Still was among a group of Georgia Republicans who signed documents falsely stating that Mr. Trump had won the state and asserting that they were “duly elected and qualified” electors on his behalf.
