Answer:
third parties
Step-by-step explanation:
aside from the fact that third parties in politics rarely ever work, some main effects of third partying politics in the US are candidates that have nothing to do with the two political parties already in office (democrat and republican). A system in which 2 major parties take control and there is no independent party (democrat and republican party). And then the winner take all system which is the party that receives the most votes takes over the office despite the other disagreeing party.
