"It's easier to fool people," Mark Twain apparently never said, "than to convince them that they have been fooled." You can find those words all over the Internet attributed to Twain, but I can locate no credible source.Too bad, because it's absolutely correct.Twain probably did say something similar, because it sounds like an opinion the acerbic author of "Huckleberry Finn" would have endorsed.I thought of Twain while watching Sen. Ted Cruz and Sarah Palin outside the White House recently, protesting the very government shutdown they'd fiercely championed -- a confederate battle flag fluttering in the background, the emblem of disgruntled losers everywhere.Is there no scam so transparently farcical that millions of American lunkheads won't fall for it? Evidently not.As you read here first, anybody with an eighth-grader's understanding of the U.S. Constitution knew that Cruz's mad quest to destroy the Affordable Care Act could not possibly succeed.
