He was a Democrat in politics and became quite popular with the poorer class of foreign immigrants who gathered in manufacturing towns and cities like Lowell. He had at first little success in politics for the reason that his party was a small minority in Massachusetts. He was elected to the House of Representatives for the Legislature of 1853. During that session there was a memorable struggle on the part of the Whigs to repeal so much of the act providing for an election of delegates to a Constitutional convention as required the election to be by secret ballot. There was also, as an incident of this struggle, an angry contest in the joint convention of the two Houses held for the purpose of electing some officers required by the Constitution to be chosen by joint ballot. The dispute related to the extent of the authority of the President of the Senate, as presiding officer, to control the joint assembly. Butler was conspicuous in that scene of turbulence and disorder. On the occasion of some ruling by the Whig Speaker, Mr. George Bliss, a worthy and respectable old gentleman, Butler called out in a loud voice: "I should like to knife that old cuss." That utterance was quoted not only all over the Union, but in foreign countries, in England, and on the continent, and in the West Indies, as a proof of the degradation and licentiousness of popular governments. It is a singular fact that a like question as to the authority of the presiding officer of a joint convention of two legislative bodies came up in Congress when the electoral vote was counted, at the time of the election of General Grant in 1868. Butler repeated on a larger stage his disorderly conduct, until Schuyler Colfax, Speaker of the House--although Mr. Wade, President of the Senate, was then presiding over the joint convention--resumed the chair of the House, in order, as Mr. Blaine described it afterward, "to chastise the insolence of the member from Massachusetts." He was chosen in 1860, when the Democratic Party was divided between the supporters of Douglas and the supporters of Breckenridge, a delegate to the National Convention at Charleston, South Carolina, by the Douglas Democrats of Massachusetts, under instructions to vote for Douglas. Instead, he voted thirty- seven times for Jefferson Davis. There has been but one other instance, I believe, in the history of Massachusetts of such a betrayal of trust. That other related not to candidates but to principles.
