candidate, former Michigan senator Lewis Cass. With the party split, Whig nominee General Zachary Taylor was easily victorious, and carried Tennessee. Johnson's relations with Polk remained poor; the President recorded of his final New Year's reception in 1849 that Johnson, due to national interest in new railroad construction and in response to the need for better transportation in his own district, also supported government assistance for the East Tennessee and Virginia Railroad. During his campaign for a fourth term, Johnson concentrated on three issues: slavery, homesteads and judicial elections. He defeated his opponent, Nathaniel G. Taylor, in August 1849, with a greater margin of victory than in previous campaigns. When the House convened in December, the party division caused by the Free Soil Party precluded the formation of the majority needed to elect a Speaker. Johnson proposed adoption of a rule allowing election of a Speaker by a plurality; some weeks later others took up a similar proposal, and Democrat Howell Cobb was elected. Once the Speaker election had concluded and Congress was ready to conduct legislative business, the issue of slavery took center stage. Northerners sought to admit California, a free state, to the Union. Kentucky's Henry Clay introduced in the Senate a series of resolutions, the Compromise of 1850, to admit California and pass legislation sought by each side. Johnson voted for all the provisions except for the abolition of slavery in the nation's capital. He pressed resolutions for constitutional amendments to provide for popular election of senators (then elected by state legislatures) and of the president (chosen by the Electoral College), and limiting the tenure of federal judges to 12 years. These were all defeated. A group of Democrats nominated Landon Carter Haynes to oppose Johnson as he sought a fifth term; the Whigs were so pleased with the internecine battle among the Democrats in the general election that they did not nominate a candidate of their own. The campaign included fierce debates: Johnson's main issue was the passage of the Homestead Bill; Haynes contended it would facilitate abolition. Johnson won the election by more than 1600 votes. Though he was not enamored of the party's presidential nominee in 1852, former New Hampshire senator Franklin Pierce, Johnson campaigned for him. Pierce was elected, but he failed to carry Tennessee. In 1852, Johnson managed to get the House to pass his Homestead Bill, but it failed in the
