Context:" <response>: The United States don turn mostly two-party system. Since conservative (like Republican Party) and liberal (like Democratic Party) dey usually di norm for American politics. Di first parties bin be Federalist and Republican, before dem split into National Republicans and Democratic Republicans. Di National Republicans become Whig Party and Democratic Republicans become Democratic Party. Whigs only last for two decades before dem split over slavery, with those wey oppose am join new Republican Party, as well as anti-slavery members of Democratic Party. Third parties (like Libertarian Party) dey usually get small support and e dey rare for dem to win elections. Despite dis, we don see some examples of third parties wey dey take votes from major parties wey people expect to win (like Theodore Roosevelt for di election of 1912 and George Wallace for di election of 1968).

So, dem third parties no dey win plenty electoral votes, even though dem fit get popular support for one state wey fit make am lean towards one party or di other. Wallace no get strong support outside South. Generally, parties wey get broad support across regions or among economic and other interest groups, get better chance to win di necessary plurality for U.S.'s mostly single-member district, winner-take-all elections. Di big land area and large population of di country dey pose serious challenges to political parties wey get narrow appeal.
