Many times a contest reaches a tipping point when one party clearly has momentum on their side. During this period, this momentum feeds itself, like a runner getting a burst of adrenalin from taking the lead. Does this mean that their success is certain? Only if their opponents accept their eventual defeat. Sudden changes can undo momentum in a moment. Balancing competitive forces tend to burn out momentum over time. All it takes is one big surprise going the other way to change everything. For example, right now, we are seeing Obama
gaining momentum at a very good time, with Super Tuesday coming up, but, if their opponents stay in the race, that momentum will change in a matter of weeks.
