Hale supported the Democratic candidates James K. Polk and George M. Dallas in the 1844 presidential election, and was renominated for his Congressional seat without opposition. Before the Congressional election, Texas annexation was adopted by the Democratic Party as part of its platform. In December 1844 the New Hampshire Legislature passed resolutions instructing its Senators and Congressmen to favor Texas annexation. Instead, Hale made a public statement opposing annexation on anti-slavery grounds.
