Yet more from Mencken (Mencken)
No one who has given any study to the development and propagation of political doctrine in the United States can have failed to notice how the belief in issues among politicians tends to run in exact ratio to the popularity of those issues. Let the populace begin suddenly to swallow a new panacea or to take fright at a new bugaboo, and almost instantly nine-tenths of the masterminds of politics begin to believe that the panacea is a sure-cure for all the malaises of the Republic, and the bugaboo an immediate and unbearable menace to all law, order and domestic tranquility.
H. L. Mencken, A Mencken Chrestomathy
