美国民众将于周二前往投票站，参加美国中期选举，这可能会将参众两院的多数党地位从共和党手中夺回给民主党。民主党掌握多数将如何改变该国政治版图，民主党又将如何采取行动遏制唐纳德·特朗普总统？
Americans head to the polls on Tuesday for the US midterm elections, which could flip the majority in one or both houses of Congress from the Republicans to the Democrats. What would a Democratic majority mean for the country's political landscape, and how might Democrats move to keep President Donald Trump in check?

若在众议院或参议院任一议院获胜，民主党将能在特朗普剩余任期内对其加以遏制，因为美国宪法赋予立法机关特定权力以制衡行政部门。
A win in either the House of Representatives or Senate would allow Democrats to rein in Trump for the remainder of his term, given that the US Constitution grants the legislature certain powers to keep the executive branch in check.
如果民主党夺取众议院控制权会有何变化 掌控下院将赋予民主党多种遏制特朗普的工具，因为众议院掌握预算提案权和国会主要调查机构——众议院监督委员会。增税立法也由众议院率先发起。
What could change if Democrats take power in the House of Representatives Taking control of the lower house would give Democrats several tools to fight Trump, as it controls budgetary initiatives and Congress’s primary investigative body, the House Committee on oversight. Legislation to increase tax revenue also starts in the House of Representatives.
拥有多数席位后，民主党将担任所有国会委员会的主席职务，这些委员会负责起草各自管辖领域的立法——其中颇具影响力的包括农业委员会和武装部队委员会。
With a majority, Democrats would assume the chairmanships of all congressional committees, which oversee the drafting of legislation for their respective jurisdictions – notably the influential agriculture and armed services committees.
委员会主席还拥有单方面启动调查和传唤证人的权力，民主党可利用这些权力强制政府官员、政治盟友或特朗普助手在宣誓作证并提供行政部门文件。
Chairmen also have the unilateral power to launch investigations and subpoena witnesses, powers the Democrats could use to compel government officials, political allies or Trump associates, to testify under oath and provide executive branch documents.
该党成员已发出信号，表明他们打算利用这项权力调查被认为从特朗普政府中获利的公司，例如人工智能企业及其掌舵的科技高管。
Members of the party have signalled their intention to use this power to investigate companies believed to have profited from the Trump administration, such as AI firms and the tech executives who run them
