Three classic quotes from Twain seem to apply very well today:
"Suppose you were an idiot. And suppose you were a member of Congress. But I repeat myself."
"All Congresses and Parliaments have a kindly feeling for idiots, and a compassion for them, on account of personal experience and heredity."
"It could probably be shown by facts and figures that there is no distinctly native American criminal class except Congress."
No this does not apply to all of them, just the overwhelming majority. And definitely to Congress as a whole for what they are doing to the American taxpayer.
