 Well, since tonight is the debate between Trump and Biden, I thought we'd take a look at some of the most famous debates in American history. In 1858, Abraham Lincoln had a series of debates with Stephen Douglas as both men were running for Senate from Illinois. The Lincoln-Douglas debates featured one speaker talking for an hour, then the other man would talk for an hour and a half, then the first speaker would get an additional 30 minutes of rebuttal time. It was during these debates on slavery that Lincoln said a house divided cannot stand, arguing that the United States would either become all slave states or all free states.
