Playwright in Twaining

I'm doing research for a play and I came across this insightful Mark Twain quote (aren't they all). As true today as ever.

"To lodge all power in one party and keep it there is to insure bad government and the sure gradual deterioration of the public morals."

-quoted in Mark Twain's Autobiography
A.B. Paine, ed. Harper, 1924.

Special bonus quote, in light of the corruption-laden scandals plaguing the current Republican-controlled Congress. Additional note: I have a shirt with this quotation, which I often wore during my tenure as a Congressional Aide. Oh, I am so subversive.

Quoth Mark Twain:

"Suppose you were an idiot. And suppose you were a member of Congress. But I repeat myself."
