在 Edexcel A-Level 政治科目中，美国政治部分要求学生理解界定民主党与共和党的关键思想与原则。这两个主要政党主导着美国的政治生活，但它们是广泛的联盟，而非高度统一的组织。它们的核心理念塑造了关于经济、社会议题、外交事务以及政府角色的政策辩论。

1. Introduction to the Two-Party System | 两党制简介

The United States has a two-party system in which the Democratic Party and the Republican Party have alternated in power since the mid-19th century. Although minor parties exist, electoral rules such as first-past-the-post and the Electoral College make it difficult for third parties to win national office. Understanding each party’s key ideas is essential for analysing US elections, policy-making, and political debate.

美国实行两党制，自 19 世纪中叶以来，民主党与共和党轮流执政。尽管存在小党，但简单多数制和选举人团等选举规则使第三党很难赢得全国性职位。理解每个政党的关键思想对于分析美国选举、政策制定和政治辩论至关重要。

2. Historical Origins of the Democratic Party | 民主党的历史起源

The Democratic Party is the oldest active political party in the world, tracing its roots to Thomas Jefferson’s Democratic-Republican Party in the 1790s. Under Andrew Jackson in the 1820s and 1830s, it became the party of the common man, opposing the national bank and supporting westward expansion. In the 20th century, Franklin D. Roosevelt’s New Deal transformed the party into a champion of federal government intervention and social welfare.

民主党是世界上现存最古老的政党，其根源可追溯至 18 世纪 90 年代托马斯·杰斐逊领导的民主共和党。在 19 世纪 20 年代和 30 年代安德鲁·杰克逊的领导下，该党成为普通民众的政党，反对国家银行并支持西进扩张。进入 20 世纪，富兰克林·D·罗斯福的新政将该党转变为联邦政府干预和社会福利的倡导者。

During the 1960s, the Democratic Party under Lyndon B. Johnson championed civil rights legislation, which shifted the party’s base towards African Americans, urban voters, and progressive activists. This realignment, combined with the rise of the New Left, cemented the party’s association with liberal and progressive principles.

20 世纪 60 年代，林登·B·约翰逊领导的民主党推动了民权立法，使该党的基本盘转向非裔美国人、城市选民和进步活动人士。这一重组加上新左翼的兴起，巩固了该党与自由主义和进步原则的联系。

3. Historical Origins of the Republican Party | 共和党的历史起源

The Republican Party was founded in 1854 by anti-slavery activists and modernisers opposed to the Kansas-Nebraska Act, which allowed slavery to expand into new territories. Its first successful presidential candidate, Abraham Lincoln, led the Union during the Civil War and signed the Emancipation Proclamation. For decades after the Civil War, Republicans were associated with big business, industrialisation, and protective tariffs.

共和党成立于 1854 年，由反对《堪萨斯-内布拉斯加法案》的反奴隶制活动人士和现代化推动者创建，该法案允许奴隶制扩展到新领土。该党第一位成功的总统候选人亚伯拉罕·林肯在南北战争期间领导联邦，并签署了《解放黑人奴隶宣言》。内战后的几十年里，共和党与大企业、工业化和保护性关税联系在一起。

In the late 20th century, under leaders such as Ronald Reagan, the Republican Party embraced supply-side economics, tax cuts, a strong national defence, and social conservatism. This coalition of economic libertarians, evangelical Christians, and national security hawks remains the backbone of the modern GOP.

20 世纪后期，在罗纳德·里根等领导人的带领下，共和党信奉供给侧经济学、减税、强大的国防和社会保守主义。这一由经济自由意志主义者、福音派基督徒和国家安全鹰派组成的联盟仍然是现代共和党的骨干。

They also emphasise a strong national defence and a strict constructionist view of the Constitution.
