During the period of the debates both were actively engaged in the State campaign, addressing one or two audiences daily, so arranging their routes as to meet at the appointed times and places. On August 21st, in presence of a vast multitude, Douglas opened the first debate at Ottawa. "Prior to 1854," he said, "this country was divided into two great political parties, known as the Whig and Democratic parties. Both were national and patriotic. * * * Whig principles had no boundary sectional line, * * * but applied and were proclaimed wherever the Constitution ruled or the American flag waved over American soil. So it was, and so it is, with the great Democratic party, which from the days of Jefferson to this period has proven itself to be the historic party of this Nation. * * * The Whig party and the Democratic party jointly adopted the Compromise measures of 1850 as the basis of a proper and just solution of this slavery question in all its forms. Clay was the great leader, with Webster on his right and Cass on his left, and sustained by the patriots in the Whig and Democratic ranks. * * * * In 1851 the Whig party and the Democratic party united in Illinois in approving the principles of the Compromise measures of 1850. * * * In 1852 the Whig party in Convention at Baltimore declared the Compromise measures of 1850 a suitable adjustment of that question. * * * * The Democratic Convention assembled in Baltimore the same year and adopted the Compromise measures of 1850 as the basis of Democratic action. * * * They both stood on the same platform with regard to the slavery question. That platform was the right of the people of each State and Territory to decide their local and domestic institutions for themselves, subject only to the Federal Constitution. "In 1854 I introduced into the Senate a bill to organize the Territories of Kansas and Nebraska on that principle which had been adopted in the Compromise measures of 1850, and indorsed by the Whig party and the Democratic party in National Convention in 1852. * * * Thus you see that up to 1854, when the Kansas-Nebraska bill was brought into Congress for the purpose of carrying out the principles which both parties up to that time had indorsed and approved, there was no division of opinion in this country in regard to that principle, except the opposition of the Abolitionists. In the House of Representatives of Illinois upon a resolution asserting that principle every Whig and every Democrat voted in the affirmative."
