In an election, there are "certain" or "lock" votes, voters who are solidly behind or
partisan to a particular candidate and will not consider changing their minds whatever the opposition says. Swing voters are undecided about how they will vote. They are sometimes referred to as
undecideds,
undecided voters, or
floating voter. Which is essentially respondents who tell pollsters that they do not know how they are going to vote in the upcoming election. They may be dissatisfied party members who are open to the idea of voting for other
parties, or they could be officially registered as "independents" or simply people who have never had a strong affiliation with any political party and will vote depending on certain things such as valance factors with may influence them:
healthcare,
benefits,
election campaign, etc. Some, but not all, swing voters are considered to be "
low-information voters." Because the votes of swing voters are considered to be "up for grabs," candidates direct a fair proportion of campaign effort towards them, but they must also be concerned with voter turnout among their political base. There is a perception that swing voters are primarily motivated by
self-interest rather than values or ideology and so are particularly susceptible to
pork barreling. If a constituency contains a large proportion of swing voters it is often called a
marginal seat and extensive campaign resources are poured into it. ==Demographics within the United States==
