After a canvas by the county clerk's office Wednesday, he lost to fellow Democrat Gregg Johnson by just 23 votes.
In a post on his Facebook page, Brooks says the results show "your vote matters."
"The next time you think about not going to the ballot box, the next time you're thinking about telling that politician or that person running for office that you're rooting for them but you may not vote, I want you think about the number 23 and how close we were to this."
Brooks says he and his supporters faced an uphill battle for the 72nd State House District, and the results send a message to party and government leaders, that they matter and should be taken into account.
"So you're right, the system does not work for us, so let's work it together. It's time to continue to show that we are no longer going to accept the status quo, and start demanding our seat at the table."
He told his supporters he accepts the results of the primary, and will not ask for a recount. But he wants the outcome to be an inspiration, and that "this is only the beginning."
