DeMarco grew up in suburban Birmingham and served as a page in the Alabama House of Representatives while in high school. He earned a bachelor's degree in journalism from Auburn University in 1990 and a Juris Doctorate from the University of Alabama School of Law in 1993, having served as editor of the Alabama Law Review. He was admitted to the Alabama State Bar that year and became a partner in the law firm of Parsons, Lee & Juliano. He served a president of the Birmingham Bar Foundation.
DeMarco won a special election on April 26, 2005 to fill the District 46 seat vacated by Mark Gaines. He was elected as the incumbent in the 2006 general election and re-elected without opposition in the 2010 general election. While in Montgomery, DeMarco co-chaired the Jefferson County Legislative Delegation. He was involved in legislation that created the position of Jefferson County Manager and opened the sale of vehicle tags to municipal offices.
In the 2014 Republican primary, DeMarco sought the 6th Congressional District of Alabama seat in the U.S. Congress left vacant by the retirement of Spencer Bachus. He garnered 39% of the primary vote, but lost to Gary Palmer by a wide margin in the runoff.
DeMarco served a term as president of the Mid-Alabama Republican Club, and was elected to succeed Butch Zaragoza as chair of the Jefferson County Republican Party in 2019. In 2021 he invited retired general and QAnon supporter Michael Flynn to address the group, and to, "talk about patriotism and public service, his military service and what we all need to do to move to keep this the greatest nation in the world."
DeMarco resides in Homewood with his wife, Jacqueline.
