I often read that in order to create a plan, you need to define your campaign strategy. What is a good definition of what the campaign strategy is all about? You can't create it, if you can't define it.
A strategy identifies 'how you will achieve your goal in a competitive environment', it should be capable of being summed up in a sentence or so. It differs from a plan, of which there may be many, that set out the steps that could be taken toward a goal or a message, that defines you, your opponent or the issues of the campaign - in fact it should help distinguish which plan of actions or messages should be chosen to achieve success. It is not about working harder or even working smarter it is an identifiable key to success in a specific race.
The best definition of campaign strategy that I have ever found is located in Chapter One of The Campaign Manual by Sal Guzzetta - see politicalpublications.net
The campaign strategy is the science or art of political command as applied to the overall planning and conduct of political campaigns. The maneuvers designed to frustrate, surprise, or overcome an opponent in order to secure a victory in an election. The plan of action that results from the practice of this science.
