As for Chase, he was undiscouraged by ill success, and shortly reaffirmed his argument and principles in the case of Driskull vs. Parish. He was at least educating the community; he was laying foundations of resistance on which walls and towers should by-and-by arise. Humanity and religion had already made the abolitionists numerically a large and active body in Ohio. They needed only a leader like Chase, of large organizing brain and solid force of combination, to shape them into a political party of great efficiency. To this end his efforts were henceforth directed. In 1841, he united in a call for an Anti-Slavery Convention in Columbus, and in this convention was organized the Liberty party of Ohio. In 1845 he projected a Southwestern Anti-Slavery Convention. The ground taken was substantially that to which a bloody, weary experience has brought the whole nation now, to wit: "That whatever is worth preserving in republicanism can be maintained only by uncompromising war against an usurping slave-power, and that all who wish to save the nation must unite in using all constitutional measures for the extinction of slavery in their own States, and the reduction of it to constitutional limits in the United States. This convention met in Cincinnati, in 1845, and Chase prepared the address, giving the history of slavery thus far, and showing the condition of the Whig and Democratic parties respecting it; and urging the importance of a political combination unequivocally committed to the denationalizing of slavery and the slave power. So vigorous were the tactics of this party, so strongly moving with the great central currents of God's forward providences, that in 1847 Chase was made Governor of Ohio, by the triumph of those very principles which in the outset threatened utter loss to their advocate. In 1847 he attended a second Liberty Convention; and afterwards took part in the Buffalo Convention, the celebrated Buffalo Platform being mainly his work. In 1849, he was chosen United States Senator from Ohio, and his presence was hailed as a tower of strength to the hard fighting anti-slavery party at Washington. When, directly after the passage of the Fugitive Slave Law, the Democratic party in Ohio voted for Pierce, knowing him directly committed to its enforcement, Chase withdrew from it, and addressed a letter to B. F. Butler, of New York, recommending the formation of an Independent Democratic party. He prepared a platform for this purpose, which was substantially adopted by the convention of the Independent Democracy of 1852.
