ALS, DLC. Thomas A. Marshall was a prominent Coles County Republican.
 George W. Rives, state representative from Edgar County, 1849-1850, and Oliver L. Davis, state representative from Vermilion County, 1851-1852 and 1857-1858, were both possible candidates. On the same date Lincoln wrote to Rives. Rives' reply of May 15, 1858 (DLC-RTL), specified that Davis was the strongest candidate and that the principal objection to Marshall was the fact that he was a banker. Marshall became the candidate, however, and was elected.
