I believe it is because the minor party, itself, cannot vote in the major party direct elections.
keep a check/balance in bills n laws presented for consideration with consideration of party platforms
Elections in which no candidate has party label
Even though it may seem like minor parties don't have much of an effect on politics and elections, minor parties can actually make enough difference to change an election. Minor parties rarely win elections but are actually necessary to politics. The small amount of people that vote for minor parties could potentially cost enough for a major party to lose an election to the other major party. For example: If an election is 50/50 between Democratic and the Republican parties and 10 percent of the Democrats decide to vote for a minor party it would cost the Democrats the election. Hope this makes sense! Good luck!
In a two party system, there exists minor parties. A minor party is a smaller, less influential political party. The two party system is when two parties control almost all the political roles. The two major parties also have a majority of the registered voters willing to vote in their party's favor. Minor parties tend to be more single focus platforms while the two major parties encompass many issues.
Third Party
The United States president must win three different elections. These elections include the party elections that allow a candidate to become the party flag bearer, the general elections, and the Electoral College elections.
A minor party is one that has very few or no officially elected members. Examples of minor parties include the Green party and the Libertarian party.
Elections in which voters determine a political party's nominee for a general election.
Lawmakers are influenced by their political party because the party allows them to represent them. The lawmakers are supported by their party.
It would probably mean a party that does not participate in elections nationally, but only in some or other region when regional elections are held.
Primary elections are needed to choose the delegates that will go to the national party conventions and elect a candidate to be that party's nominee for the general election. General elections are to select electoral college delegates who will vote for one party's nominee.
