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.[47]
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.[48] 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.
