Puerto Rico
In Puerto Rico, where SNTV is known as at-large representation ("representación por acumulación" in Spanish), political parties vary the ballot order of their candidates across electoral divisions, in order to insure each candidate has a roughly equal chance of being elected. Since most voters choose the candidates placed at the top of their party lists on the ballots they receive, at-large candidates from the same party usually obtain approximately equal vote totals.
The two major Puerto Rican political parties, the Popular Democratic Party and the New Progressive Party, usually nominate six candidates for each chamber, while the much smaller Puerto Rican Independence Party runs single-candidate slates for both the Senate and the House of Representatives. However, the overall distribution of legislative seats is largely determined by the results for the sixteen Senate and forty House district seats, elected by Plurality voting.
Taiwan
In Taiwan, the party structure is further complicated by the fact that while legislators are elected by SNTV, executive positions are elected by a First Past the Post. This has created a party system in which smaller factionalized parties, which SNTV promotes, have formed two large coalitions that resembles the two party system, which First Past the Post promotes.
