Is it fair that third party candidates take away from the two political parties why or why not

it is fair, third party candidates decide who to vote for so there would be a competition between the Democratic party and the Republican party it is also not fair because even though you can vote for a third party candidate, they cannot win the election so if you vote for a third party candidate, you are basically wasting your vote.

Explanation:

the answer would be a i think?
