He edited anti-slavery journals the "Republican" (published in Hartford) and the "Commonwealth" (published in Boston), and from 1859 became the owner and editor of the "Worcester Spy," what George Frisbie Hoar called "one of the most influential papers in New England."From this time onwards Baldwin was resident in Worcester, Massachusetts. He was a delegate to the 1860 Republican National Convention, where Abraham Lincoln was nominated as Republican presidential candidate, and in 1863 he was elected to the U.S. House of Representatives for Massachusetts's 8th congressional district.
