美政府面临关门危机，两党为拨款法案争执，特朗普紧急会晤党领袖

Group 1 - The core issue is the dramatic 92% drop in soybean imports from the U.S. to China, which has severely impacted the agricultural sector and shaken the confidence of voters in the Midwest who previously supported Trump [1][13][24] - The crisis is exacerbated by a combination of factors including the trade war's backlash, significant damage to the agricultural economy, and increasing partisan divisions, leading to a potential government shutdown affecting around 800,000 federal employees [5][11][21] - The political landscape is shifting, with Trump needing to negotiate with Democrats to pass funding bills, indicating a significant weakening of his authority and support within the Republican Party [17][18][20] Group 2 - The agricultural market is facing a critical situation as the U.S. soybean exports to China have nearly ceased, with South American countries like Brazil and Argentina filling the void, leading to a collapse in soybean prices and threatening the viability of many family farms [14][24] - The government's inability to maintain basic functions raises questions about the U.S. political system's resilience and its capacity to respond to global challenges, highlighting a disconnect between governance and public needs [21][22][26] - The trade war initiated by Trump, aimed at reshaping international trade dynamics, has backfired, resulting in significant harm to the U.S. agricultural market and demonstrating the consequences of policies that disregard market realities [24][26]
