what type of party system does mexico have?
multi-party system
a so-called "third party" in the united kingdom are the liberal democrats. in the 2010 election, the liberal democrats received 23% of the votes but only 9% of the seats in the house of commons. while electoral results do not necessarily translate into legislative seats, the liberal democrats can exert influence if there is a situation such as a hung parliament. in this instance, neither of the two main parties (at present, the conservative party and the labour party) have sufficient authority to run the government. accordingly, the liberal democrats can in theory exert tremendous influence in such a situation since they can ally with one of the two main parties to form a coalition. this happened in the coalition government of 2010. yet in that more than 13% of the seats in the british house of commons are held in 2011 by representatives of political parties other than the two leading political parties of that nation, contemporary britain is considered by some to be a multi-party system, and not a two-party system. the two party system in the united kingdom allows for other parties to exist, although the main two parties tend to dominate politics; in this arrangement, other parties are not excluded and can win seats in parliament. in contrast, the two party system in the united states has been described as a duopoly or an enforced two-party system, such that politics is almost entirely dominated by either the republicans or democrats, and third parties rarely win seats in congress.
two-party system
there is general agreement that the united states has a two-party system; historically, there have been few instances in which third party candidates won an election. in the first party system, only alexander hamilton's federalist party and thomas jefferson's democratic-republican party were significant political parties. toward the end of the first party system, the republicans dominated a one-party system (primarily under the presidency of james monroe). under the second party system, the democratic-republican party split during the election of 1824 into adams' men and jackson's men. in 1828, the modern democratic party formed in support of andrew jackson. the national republicans were formed in support of john quincy adams. after the national republicans collapsed, the whig party and the free soil party quickly formed and collapsed. in 1854, the modern republican party formed from a loose coalition of former whigs, free soilers and other anti-slavery activists. abraham lincoln became the first republican president in 1860.
