People on both sides of the issue were out on Saturday, trying to convince voters how to cast their ballots.
In Seattle, participants in an R-74 rally said they are promoting peace and acceptance for all. They hope that voters will say yes to the measure, which would uphold the state Legislature's vote earlier this year to allow same-sex marriage.
Imagine, they say, what it's like to walk a mile in their shoes.
"I can't even believe that we have to sit here and raise all this money to fight for something that should just be," says R-74 supporter Ceasar Hart.
"It doesn't matter if two women or two men want to get married - it's none of anybody's business," agrees another R-74 supporter, Kelsey Ward.
Hundreds of R-74 proponents marched for marriage equality through Capitol Hill.
"It's to bring about visibility and to show the community that we are here, have a voice and (are) ready to make some change here," Sarah Toce said at the rally.
At the same time in Everett, there was a much smaller demonstration, but with a stance that participants said is just as important - do not redefine "marriage."
"Gays and lesbians can live any way they want to, but they have no right to redefine marriage," says R-74 opponent Chuck Whitfield.
Whitfield says his side of the issue is often mislabeled as hateful.
"In order to show love and compassion to gays and lesbians, we want to do it kind and in a manner that is pleasing to the Lord," says Whitfield.
The November election is less than a month away - it is then we will see the final fate of Referendum 74.
A "yes" vote on R-74 is to uphold the state Legislature's vote earlier this year to allow same-sex marriage and a "no" vote is to overturn it.
