to prevent the formation of opposition to Martin Van Buren. Twenty-two states and two territories were represented at the convention with Alabama, Illinois, and South Carolina being unrepresented. The delegate amount per state varied from Maryland having 188 delegates to cast its ten votes while Tennessee's fifteen votes were cast by one delegate. The convention saw the first credentials dispute in American history with two rival delegations from Pennsylvania claiming the state's votes. The issue was solved by seating both delegations and having them share the state's votes. An attempt to remove the two-thirds requirement for the selection of a candidate was passed by a vote of 231 to 210, but was later restored through a voice vote. Some Southerners opposed Johnson's nomination, due to his open relationship with an enslaved woman, whom he had regarded as his common-law wife. At the convention, Van Buren was nominated unanimously with all 265 delegates in favor, but the Virginia delegates supported Senator William Cabell Rives against Johnson. However, Rives got little support and Johnson was nominated with one more vote than the two-thirds requirement. Whig Party nomination The Whig Party emerged during the 1834 mid-term elections as the chief opposition to the Democratic Party. The party was formed from members of the National Republican Party, the Anti-Masonic Party, disaffected Jacksonians, and small remnants of the Federalist Party (people whose last political activity was with them a decade before). Some Southerners who were angered by Jackson's opposition to states' rights, including Sen. John C. Calhoun and the Nullifiers, also temporarily joined the Whig coalition. Unlike the Democrats, the Whigs did not hold a national convention. Instead, state legislatures and state conventions nominated candidates, being the reason why so many candidates from the Whig party ran in the general election. Southern Nullifiers placed Tennessee Senator Hugh Lawson White into contention for the presidency in 1834 soon after his break with Jackson. White was a moderate on the states' rights issue, which made him acceptable in the South, but not in the North. The state legislatures of Alabama and Tennessee officially nominated White. The South Carolina state legislature nominated Senator Willie Person Mangum of North Carolina. By early 1835, Massachusetts Senator Daniel Webster was building support among Northern Whigs. Both Webster and White used Senate debates to establish their positions on the issues of the day, as newspapers carried the text of their speeches nationwide.
