Money quote: “Like an army, a political party must be coherent and disciplinedto be effective, and these qualities alone can carry the day, even against greater numbers.”

And man, the Republican Party today, while seen by some as defeatist, intellectually bankrupt, and extremist to the point of being irrational, are really disciplined. And, hard as this is to admit, they are incredibly coherent about their message, whatever feelings you have about the truth or candor of the message itself.
