The Mexican American War Congressional Debate
A Gag on Debating the Resolution Forced a Vote in One Afternoon
On May 11, 1846, President James K. Polk sent a war message to the Congress declaring that “war exists…by the act of Mexico herself.” After one afternoon of “debate” in the House, during which opposition was silenced by a gag on meaningful debate, a war resolution was swiftly passed. Although the Senate took longer to approve the measure, South Carolina’s John C. Calhoun would later say that had the documents relevant to the president’s message been given proper scrutiny, less than 10% of the Congress would have voted for war.
“Hostilities May Now be considered as Commenced”
President Polk’s desire to annex Mexico’s North American provinces began with a diplomatic mission to Mexico City led by John Slidell. The Mexican leadership, however, refused to meet with Slidell. At the same time, Polk ordered Brigadier General Zachary Taylor to move his army, then stationed in Texas, across the Nueces River in January 1846.
Taylor’s troops crossed into the disputed territory, arriving at the Rio Grande. Mexicans regarded the disputed territory as theirs. Even the 1845 Annexation Resolution bringing Texas into the Union accepted the Nueces River as the proper boundary. When debate began on the war resolution, this would be a key factor for many Congressmen, including Missouri Senator Thomas Hart Benton who expressed his concerns to Polk at the White House hours before the crucial vote.
American troops constructed a fort on the hills overlooking the Mexican port city of Matamoros and aimed cannons at the city. At the same time, American warships were ordered to the Mexican coast off Vera Cruz. On April 24th, Mexican troops crossed the Rio Grande and engaged American dragoons, killing three.
John Slidell returned to Washington one day before news of the military encounter reached Polk. Even before this news, Polk and the majority of his Cabinet were willing to send a war message to Congress. Zachary Taylor’s skirmish with the Mexican army made a war message all the easier.
“Forced into a Conflict with a Semi-Barbarous People”
Thus stated a passage in the House Committee on Foreign Affairs. Yet House Whigs, in the minority, and supported by a handful of dissident Democrats, rejected the president’s claims. 114 pages of documents sat on the Speaker’s desk yet only a select few were read in the chamber. Neither the House nor the Senate were allowed adequate time to fully review the documents. Once a gag on debate was imposed in the House, Whigs used Parliamentary Procedure to voice their arguments, most notably regarding the preamble of the war bill which made Mexico the aggressor.
Members were recognized with a “point of personal privilege” which takes parliamentary precedence in debate and is usually used to receive permission to leave the chamber. Once recognized, however, these members used their time to berate the war message and demand scrutiny of all the accompanying documents.
The Senate debate was just as short, spending only one day on the measure. As in the House, senators were not afforded the time to hold committee hearings or read all of the documents. Senator Calhoun abstained from voting while others voted taking exception to the preamble.
War Divides the Nation
The lack of public debate affected public perceptions. Writers like Emerson and Whitman supported the war while Thoreau refused to pay taxes in protest. Some Americans, agreeing with Polk, favored annexing Mexico while others were content to own “uninhabited” land ripe for expansion.
The lack of proper debate led the United States down a slippery path that still causes ill feelings between Mexico and America. Yet the past has been repeated too often in history, as Congress responded emotionally without consulting all relevant facts.
