At 26, he will be one of the youngest members of Iowa’s state senate. Whals will also be joining the same body he spoke to n 2011, starting his career as an activist.

Wahls was conceived by his lesbian mothers using artificial insemination, and fought to promote same-sex marriage since his high school years.

His testimony during a public hearing on a constitutional amendment to ban same-sex marriage in the state went viral in early 2011

In late 2011, he also wrote the book titled “My Two Moms” that focuses on his upbringing.

Wahls plans to focus on affordable health care, including pushing back on a 2016 move by republicans that privatized Medicaid in Iowa. He also intends to work on education funding and worker’s rights.
