Answer:
The United States has a long history of supporting Taiwan, which is a self-governing island that China claims as its own territory. The US has sold Taiwan billions of dollars in arms and has pledged to defend the island if it is attacked by China.
The US is concerned about the Taiwan election because it could have implications for the future of the relationship between the US and China. If the pro-independence Democratic Progressive Party (DPP) wins the election, it could lead to increased tensions between the US and China. The DPP has said that it is willing to defend Taiwan's independence, which could provoke China to take military action.
The US is also concerned about the Taiwan election because it could have implications for the future of democracy in Taiwan. The DPP is a pro-democracy party, and if it wins the election, it could help to strengthen democracy in Taiwan. However, if the Kuomintang (KMT), a pro-China party, wins the election, it could lead to a decline in democracy in Taiwan.
The US is closely watching the Taiwan election because it is a critical event that could have far-reaching implications for the future of the US, China, and Taiwan.
