Can you quote him? In his book, Tip O'Neill said that the election of Ronald Reagan was a "sinful." Tip O'Neill despised Ronald Reagan even if he might have found him personally amusing. Reagan rode herd over the Congress in his first term, and O'Neill was powerless to do anything about it. Reagan was also proved right in his "peace through strength" foreign policy, and proved the utter stupidity and anti-Americanism of O'Neill's "peace through concession" strategy in dealing with te Soviets.
I believe I read it in Chris Matthews book. I know from numerous sources that Tip O'Neill and Reagan used to play poker together.
