Make the opponents' goal more expensive than it's worth. Give 'em a title and get 'em involved. Expand the leadership. You can't beat a plan with no plan. Political technology determines political success.
Sound doctrine is sound politics.
Keep your eye on the main chance and don't stop to kick every barking dog. Don't make the perfect the enemy of the good. Remember the other side has troubles too. A well-run movement takes care of its own. Hire at least as many to the right of you as to the left of you.
