共和党分歧加剧，美参议院暂停审议“大漂亮”法案

Core Viewpoint - The U.S. Senate has paused the deliberation of the "Big Beautiful" bill due to significant internal divisions within the Republican Party, with efforts ongoing to secure enough votes for passage [1][2]. Group 1: Legislative Process - The Senate's complex process requires handling all proposed amendments before a final vote on the bill can occur, with key amendments potentially influencing overall support [2]. - The Senate is expected to continue voting on numerous amendments, which are critical to determining the bill's fate [2]. Group 2: Internal Party Divisions - Key points of contention within the Republican Party include substantial cuts to social security spending, the retention of clean energy tax credits, and the overall fiscal deficit of the bill [1][2]. - Eight Republican senators are currently considered potential dissenters, with Rand Paul and Thom Tillis being the most prominent opponents [1]. Group 3: White House Involvement - The White House is actively lobbying for votes, with President Trump personally making calls and warning of historical tax increases if the bill fails [3]. - Treasury Secretary Mnuchin is optimistic about the bill's approval in the near term, while Senate Majority Leader John Thune remains cautious about progress [3]. Group 4: Clean Energy Subsidies - The current version of the bill proposes significant reductions in subsidies for clean energy, which has led to dissatisfaction among some Republican senators [4]. - A proposed amendment aims to relax the completion deadline for projects seeking subsidies, but this could provoke backlash from fiscal conservatives [4]. Group 5: Healthcare Funding Controversies - The bill's proposed cuts to Medicaid have sparked controversy, particularly among rural representatives concerned about hospital closures [6]. - A Republican senator's amendment to increase funding for rural hospitals was rejected by Democrats, highlighting the contentious nature of healthcare provisions in the bill [6]. Group 6: Final Amendments and House Considerations - The Republican leadership is preparing a "last resort amendment" to balance internal party opinions before the final vote, which must also consider the House's acceptance of any changes [7]. - The House previously passed its version of the bill by a narrow margin, and the Senate's more aggressive cuts to Medicaid could complicate support from moderate Republicans in the House [7].
