Caubble, of Wynne, was 65.
The Republican Party of Arkansas Chairman Doyle Webb released the following statement on Caubble's passing:
"Our party is deeply saddened by the passing of Tommy Caubble. Our prayers go out to the Caubble family and all who knew Tommy. Tommy died of a heart attack while spending time in his family's peach orchard as he did every morning. Tommy loved his community and state and wanted nothing more than to serve others in hopes of making the place he loved better for all Arkansans. His positive outlook, sense of humor and kind spirit will be missed by all. We ask that everyone pray for Tommy's family and keep them in your thoughts."
