He was initially running for the Arkansas House of Representatives, District 10. However, he switched to run for the Arkansas State Senate, District 25, because there were only two Democrats running for the seat, as opposed to the one Republican and three Democrats running for the house seat.
Dinwiddie graduated from SEARK College as a Paralegal. He served in the United States Navy from 1985-1999. He currently works as an auto mechanic and small business owner.
Dinwiddie has stated the following: ""Tax Breaks don't lower taxes because they will just make it up somewhere else. Cutting Spending does not eliminate waste because, what gets cut is not what's wasteful. What gets cut is that with least resistance. Example 2011 when they cut funding to foster kids."
