📚 Relationships between the Presidency and Congress | 总统与国会的关系
In the US system of separated powers, the presidency and Congress are not arranged in a simple hierarchy. The Constitution creates separate institutions that share powers, so cooperation and conflict are both normal. This article explains the formal and informal relationships between the two branches, with a focus on Edexcel A-Level Politics requirements.
在美国的分权体制下，总统与国会并非简单的上下级关系。宪法建立了相互独立但共享权力的机构，因此合作与冲突都是常态。本文解析两大分支之间的正式与非正式关系，紧扣 Edexcel A-Level 政治考点。
1. Constitutional Foundations: Separation of Powers and Checks and Balances | 宪法基础：权力分立与制衡
Article I vests all legislative powers in Congress, while Article II vests executive power in the president. The Framers deliberately created overlapping powers rather than a watertight separation, so each branch has constitutional tools to check the other. Neustadt famously described the system as “separated institutions sharing powers”, meaning that influence often depends on persuasion rather than command.
宪法第一条将立法权授予国会，第二条将行政权授予总统。制宪者刻意让权力交叉而非绝对分离，使每个分支都有宪法工具制衡对方。诺伊施塔特将这种体制描述为”相互独立但共享权力的机构”，这意味着影响力往往取决于说服而非命令。
- President may veto legislation; Congress may override by two-thirds. 总统可否决议案；国会可以三分之二多数推翻。
- Senate confirms key appointments and treaties. 参议院批准重要任命和条约。
- House can impeach; Senate can convict and remove. 众议院可弹劾；参议院可定罪并罢免。
2. Shared Legislative Powers: Presidential Recommendation and Veto | 共同立法权：总统建议与否决权
The president cannot introduce bills directly in Congress, but the annual State of the Union message and the executive budget proposal set the legislative agenda. Once both chambers pass an identical bill, the president may sign it, veto it, or allow it to become law without signature. A regular veto returns the bill with objections; Congress can override with a two-thirds vote in both the House and the Senate. A pocket veto occurs when the president does not sign a bill within ten days while Congress adjourns, killing the bill without a formal veto.
总统不能直接在国会提出法案，但年度国情咨文和行政预算提案为立法议程定调。当两院通过相同文本后，总统可以签署、否决或不予签署使其自动成为法律。常规否决会将法案退回并附反对理由；国会如要推翻，需在众议院和参议院均达到三分之二多数。口袋否决发生在国会休会期间，总统在十天内不签署法案，法案即自动作废，无需正式否决。
3. Confirmation and Treaty Powers over the Executive | 国会对行政分支的人事确认与条约批准权
The Senate must confirm presidential appointments to the Cabinet, federal courts, and ambassadorships by a simple majority vote. Treaties require a two-thirds vote in the Senate, making foreign policy a shared power. Presidents often use executive agreements instead, which do not require Senate approval but can be less durable.
参议院以简单多数批准总统提名的内阁成员、联邦法官和大使。条约需要参议院三分之二批准，因此外交政策是共享权力。总统常用行政协定代替条约，这种协定无需参议院批准，但效力可能较短。
4. The Power of the Purse: Congressional Control of Funding | 财政权：国会控制拨款
Congress holds the “power of the purse” because only it can appropriate money. The president submits a budget request, but Congress may amend, delay, or refuse funding for executive priorities. If no appropriations bill is passed, parts of the federal government may shut down. The 1974 Congressional Budget and Impoundment Control Act further limited the president’s ability to refuse to spend appropriated funds.
国会掌握”财政权”，因为只有它有权拨款。总统提交预算请求，但国会可以修改、推迟或拒绝为总统优先事项提供资金。如果拨款法案未能通过，部分联邦政府可能停摆。1974年《国会预算与扣留控制法》进一步限制总统拒绝使用已拨款项的能力。
5. War Powers: Commander-in-Chief vs Congress’s Power to Declare War | 战争权力：总司令与国会宣战权
The Constitution gives Congress the power to declare war, but the president as commander-in-chief controls the armed forces. Since 1941, formal declarations of war have been rare; presidents have used military force without declarations in Korea, Vietnam, Iraq, and elsewhere. The 1973 War Powers Resolution requires the president to notify Congress within 48 hours and withdraw forces after 60 days unless Congress authorises continued action.
宪法赋予国会宣战权，但总统作为总司令控制军队。1941年以来，正式宣战已很罕见；总统在朝鲜、越南、伊拉克等地未经宣战即使用武力。1973年《战争权力决议》要求总统在48小时内通知国会，并在60天内撤军，除非国会授权继续行动。
6. Oversight and Investigation: Hearings, Committees and Impeachment | 监督与调查：听证会、委员会与弹劾
Congress exercises oversight through standing committees, select committees, hearings, subpoenas, and investigations. The Government Accountability Office and inspectors general support this role. The ultimate check is impeachment: the House may impeach by a simple majority, and the Senate may convict and remove by a two-thirds vote. Presidents Nixon, Clinton, and Trump faced impeachment proceedings, though none was removed from office.
国会通过常设委员会、特别委员会、听证会、传票和调查行使监督权。政府问责局和监察长支持这一职能。最终制衡是弹劾：众议院以简单多数发起弹劾，参议院以三分之二多数定罪罢免。尼克松、克林顿和特朗普都曾面临弹劾程序，但无人被罢免。
7. Party Control and Divided Government | 政党控制与分裂政府
Unified government occurs when the president’s party controls both chambers of Congress, often making it easier to pass major legislation. Divided government occurs when at least one chamber is controlled by the opposition, increasing gridlock and veto threats. However, divided government can also produce bipartisan compromises, such as welfare reform in 1996 or the 2013 budget deal.
当总统所属政党同时控制国会两院时，即为”统一政府”，通常更容易通过重大法案。当至少一个议院由反对党控制时，即为”分裂政府”，更可能出现僵局和否决威胁。但分裂政府也能促成两党妥协，如1996年福利改革或2013年预算协议。
8. Executive Orders and Congressional Responses | 行政命令与国会回应
Presidents use executive orders, proclamations, and signing statements to pursue policy without new legislation. Congress can respond by passing a law to overturn or restrict an executive order, by withholding funding, or by amending the underlying statute. Courts may also strike down executive actions as unconstitutional. For example, Congress attempted to block Trump’s border emergency declaration, but a veto prevented the resolution from becoming law.
总统利用行政命令、公告和签署声明在不需新立法的情况下推进政策。国会可以通过立法推翻或限制行政命令、扣押资金或修改相关法律来回应。法院也可裁定行政措施违宪。例如，国会曾试图阻止特朗普的边境紧急状态声明，但总统否决使得决议未能生效。
9. The Changing Balance: Imperial Presidency vs Resurgent Congress | 变化的平衡：帝王总统与国会复兴
Historians and political scientists debate whether the presidency has become too powerful. Arthur Schlesinger’s “imperial presidency” thesis argued that presidential power, especially in foreign policy and war, grew beyond constitutional limits. Congress attempted to reassert itself in the 1970s through the War Powers Resolution, the Budget Act, and stronger oversight. In recent decades, partisan polarisation and divided government have again shifted the balance back and forth.
历史学家和政治学家争论总统是否权力过大。阿瑟·施莱辛格的”帝王总统”论认为，总统权力尤其是外交和战争权力已超出宪法限制。国会于20世纪70年代通过《战争权力决议》、《预算法》和加强监督试图重振自身。近几十年来，党派极化和分裂政府又使权力天平不断反复。
10. Exam Evaluation: How to Assess the Relationship | 考试评估：如何评价两者关系
In an exam answer, avoid claiming that one branch always dominates. The relationship is dynamic and shaped by party control, public opinion, national crises, personalities, and the specific policy area. A strong evaluation will contrast formal constitutional powers with informal political resources such as the president’s “bully pulpit”, media attention, and party discipline. Use recent examples to support both conflict and cooperation.
在考试答案中，避免断言某一分支始终占主导。两者关系是动态的，受政党控制、公众舆论、国家危机、个人风格以及具体政策领域影响。高质量的评估应对比正式宪法权力与非正式政治资源，如总统的”头号讲坛”、媒体曝光和政党纪律。使用近期例子支持冲突与合作两种情形。
