Buchanan in his Lecompton policy, which was believed to be in direct contradiction to the principle of popular sovereignty, upon which he was elected, brought out the indignant opposition of a portion of his northern and western supporters, and their representatives in Congress, prominent among whom was Mr. John B. Haskin,the member from the Ninth District of New York, in which was Westchester County. In the Congressional election of 1858, in this District, the course of the administration was made the issue, and Mr. Gouverneur Kemble, having been nominated by the Democratic party, Mr. Haskin was placed by his friends in the political field. He was supported by the Republicans, and elected, by a small majority, over his opponent. To this election, and that in the sixth district of Pennsylvania, where Mr. Hickman, an associate of Mr. Haskin, was in like manner opposed by the whole strength of the administration, the eyes of the whole country were turned. Said a gentleman from Morrisania, "Should Mr. Haskin be defeated, and an administration candidate be elected, every post-office and every office of the Government would be illuminated." An incident in Congress, of a startling nature, in the early part of 1860, brings to notice the continued, determined and ardent part taken, after his re-election, by the representative of Westchester County in the fulfilment of his duties. While addressing the House Mr. Haskin accidentally let fall from the breast pocket of his coat a loaded revolver. On the question of the propriety of carrying this weapon into the House, not only in Congress, but among his constituents and throughout the country, warmest discussions followed. The e.xplanation given was preparation for self-defense in the unprotected neighborhood in Washington, in which Mr. Haskin resided, in which much lawlessness prevailed.
