On the question of the gentlemanliness of the debate, I'm reminded that in the Congress, just before the Civil War, the Senator from New Hampshire, I think, made an anti-slavery speech, and a Senator from Mississippi, not Jefferson Davis, invited him to come down to Mississippi to make that speech, promising to see that he was hanged from the highest tree in the forest. The Senator from New Hampshire invited the Senator from Mississippi to come to New Hampshire where he would be given a respectful hearing in every township in that State.
