Congress responded to lincoln's ten-percent plan, as it was known, by passing the

Wade-Davis Bill in the summer of 1864. The Bill was passed by the Radical Republicans because they thought the ten-percent plan was too lenient. The Bill made readmission into the Union more difficult by requiring the majority voters in each southern state to take The Ironclad Oath, denouncing the Confederacy. The ten-percent plan only required 10% of the 1860 vote count to have pledged allegiance to the Emancipation.
