The Tyler-Texas annexation treaty, submitted to the Senate in April 1844, was defeated in the Whig controlled Senate, largely along partisan lines, 16 to 35 – a two-thirds majority against passage – on June 8, 1844. Whigs voted 27–1 against the treaty: all northern Whig Senators voted nay, and fourteen of fifteen southern Whig Senators had joined them. Democrats voted for the treaty 15–8, with a slight majority of Northern Democrats opposing. Southern Democrats affirmed the treaty 10–1, with only one slave state Senator, Thomas Hart Benton, voting against.
