Impact on campaigning
Focusing only on the undecided voters instead of all voters at large is a core part of almost all political campaigns. With this framework in mind, the idea of a swing vote can closely tie with the concept of swing states. Swing/Battleground states are states that neither party can guarantee will go in their favour. These are the states that politicians will most likely focus their time to maximize their reach, in the same way that there is a focus on swing voters. Identifying battleground states is much easier than identifying individual swing votes.
