In 1867, Henry Blackwell proposed a solution: convince southern political leaders that they could ensure white supremacy in their region by enfranchising educated women, who would predominantly be white. Blackwell presented his plan to politicians from Mississippi, who gave it serious consideration, a development that drew the interest of many suffragists. Blackwell's ally in this effort was Laura Clay, who convinced the NAWSA to launch a campaign in the South based on Blackwell's strategy. Clay was one of several southern NAWSA members who objected to the proposed national women's suffrage amendment on the grounds that it would impinge on states' rights.
