I would like to take issue with one thing which BLatham has written, to the effect that political discourse has gotten nastier. What i'm going to post is not posted for it's imflamatory content, but simply as some evidence of my contention that political discourse has always had it's feet in the gutter, even when its head were in the clouds:
(From the 1860 Presidential campaign)
Nasty, even viciously insulting political graffitti has been found on the walls of Pompei and Herculaneum, and in more sheltered parts of walls of ruins in Rome. I imagine that were one able to excavate the walls of a city in ancient Akkadia which were as well preserved as those at Pompei, one would find much the same thing.
Political discourse has always been very, very nasty . . . it has only recently benefited from electronic sophistication . . .
