In selling, the character trait of patience is at least as important as, and probably more important than, chutzpah. Customers are more likely to buy from people who have the ability to listen and to empathize than from people who are obsessed with closing a deal.
You can see politics as competition - destroying your opposition - or you can see it as sales. You can agitate voters into voting against, but only in the absence of meaning. What earns the people's trust, though, isn't knowing what you stand against, but what you stand for.
Naturally, people want to know you stand for them. Voters are always more likely to buy from and come back to the Party that listens to and empathizes with them.
