Question

what is the outcome for most third party candidates?
they make an impact but do not win.
they become influential power brokers.
they come back as republicans or democrats.

Explanation:

In the U.S. two-party political system, third party candidates rarely win major elections, but they can bring attention to overlooked issues, influencing the platforms of the two major parties. Only a tiny number become power brokers or join major parties, so this is not the typical outcome.

Answer:

They make an impact but do not win.
