After the war Simpson moved to Shelby County, Kentucky where he would study law and become one of Shelby County's first attorneys.[7] He went on to be elected to the Kentucky House of Representatives representing Shelby County. He was elected to 4 consecutive terms from 1806 to 1811.[6] He was elected Speaker of the House from 1810 to 1811; defeating Samuel South and William MacMillan.[8]
In 1812 he was elected to the United States House of Representatives from the newly created 8th District of Kentucky. Although the 8th district had just been formed he defeated incumbent Stephen Ormsby who had been redistricted from the 3rd. He defeated Ormsby by a 'small margin'.[9] Before taking his seat the War of 1812 broke out and Simpson rejoined the army. Ormsby would later win a special election to be his replacement.[10]

During the War of 1812 Simpson once again volunteered for service. On August 15, 1812 [1] he joined the First Rifle Regiment using his political clout to become the Captain of the regiment's third company.[5] Under the command of Col. John Allen his regiment helped reinforce Gen. Hull in Detroit.[4] He participated in the Battle of River Raisin on January 22, 1813. He joined the battle during a British counterattack while the regular soldiers where retreating to the river. While his company only lost one soldier during its first engagement[11] he was killed early into the retreat.[1] In September 1834 human remains believed to be his were exhumed and returned to Kentucky. However, they have never been positively identified. He is also believed to have been reburied in the Frankfort Cemetery in Frankfort, Kentucky but the exact location is unknown.[3]
