Please feel free to listen to it in its entirety, but I was particularly impressed with the quality of the speech itself. Kudos to that speechwriter as it mixed a nice balance of rousing rhetoric with practical details. Initially, I thought that reference to the 106 year old woman was going to be cliched and altogether hackish, but it proved a good vehicle for walking through the American history of the 20th century.
I am of the opinion that political speechwriting is the borderline equivalent of playwriting in the 1920s. Good writers are drawn there.
