When Warren G. Harding ran for president in 1920, he ran his entire campaign from his home in Marion, Ohio. It was known as the Front Porch Campaign. In preparation for the campaign, the home was substantially renovated and modernized. The renovations in 1920 included the full remodeling of the second floor bathroom, the redecorating of the Library and Parlor, and the construction of an addition onto the kitchen.The project was conducted for the Ohio History Connection and was successful in identifying the foundation of the former 1920 wing addition. The intact foundation was found to be a poured concrete base that was topped by concrete block. The outline of the foundation encloses a 12ft by 12ft area. In addition to the foundation the test unit excavations resulted in the identification and/or recovery of 10,282 historic artifacts, three prehistoric artifacts and several features associated with former structural features. These features relay significant information on the former kitchen wing and/or use of the rear yard area.
