William Henry Seward was one of the US's more important politicians during the antebellum period and eventually the Civil War, being elected governor of (in 1838) and later senator from (1849) the state of New York. After being defeated in his attempt to become the Republican Party's presidential nominee in 1860 by Abraham Lincoln, he became his Secretary of State.
So here's the potential (and obscure) POD: Seward ran for governor in 1834 (four years earlier than his eventual victory IOTL), but was very narrowly defeated by the incumbent Democrat William L. Marcy. What if he was elected? First, this would mean that he gets more time to become a major national figure (not that he wasn't IOTL) since he would be only 33 years old by the time he took office.
Could this somehow affect the 1836 presidential election, which was won by Martin Van Buren IOTL? New York was his home state, after all, and having a Whig governor (who would probably campaign for Harrison) could mess things up in there.
