With 43 days until the election, all this week we're focusing on the social issues most important to voters.
Tonight we'll discuss gay marriage, which was number five on our poll of top domestic issues for registered voters.
You'll hear from Zach Wahls of Iowa, whose speech entitled "What Makes a Family" in support of gay marriage to his state legislature went viral on the internet last year.
He's the son of two lesbian mothers and author of the book "My Two Moms."
"My family really isn’t so different from any other Iowa family," Wahls told state lawmakers. "We just hope for equal and fair treatment for our government," he added.
Most recently, Wahls spoke last month at the Democratic National Convention in Charlotte, North Carolina.
"People want to know what it's like having lesbian parents. I'll let you in on a secret: I'm awesome at putting the seat down. Otherwise, we're like any other family," Wahls told delegates. Watch the video for more of his speech.
Hear from Wahls tonight on AC360° and each day this week we'll countdown to the #1 social issue for voters. Don't miss our special election coverage tonight at 8 and 10 p.m. ET.
