今年美国众议院的所有议席都将面临改选，选举结果是对选民在总统唐纳德·特朗普第二个任期开始近两年之际对其感受的一次重大检验。
Every seat in the US House is on the ballot this year, and the results are a major test of how voters feel almost two years into President Donald Trump’s second term.
为了衡量这一点，美国有线电视新闻网正在将每个选区的众议院选举结果与该选区在2024年总统选举中的投票情况进行比较。例如，如果特朗普在一个选区以10个百分点的优势获胜，而这次共和党众议员候选人以4个百分点的优势获胜，这就代表着向民主党方向转变了6个百分点。
To measure that, CNN is comparing each district’s House result with how it voted for president in 2024. If Trump won a district by 10 points, and the Republican House candidate carried it by 4 this time, that would represent a 6-point shift toward Democrats, for example.
这不是一个完美的比较。众议院竞选并非总统竞选。连任优势、地方议题以及候选人本身都很重要，而且通常在中期选举中投票的人较少。但在数百个选区中，这些转变是国家正在向哪个方向移动的最清晰信号之一。
It’s not a perfect comparison. A House contest isn’t a presidential race. Incumbency, local issues and the candidates themselves all matter — and fewer people generally vote in midterms. But across hundreds of districts, these shifts are among the clearest signals of which direction the country is moving.
结果将自动更新并反映在下方。早期的统计结果可能会产生误导，随着计票工作的继续，选区情况可能会发生剧烈摆动。这就是为什么地图仅显示预计选票已完成至少30%的选区。
The results will update and reflect automatically below. Early returns can be misleading, and districts can swing sharply as the counting continues. That’s why the map shows only districts with at least 30% of the expected vote in.
请在选举之夜查看并关注结果的陆续出炉——这些图表将在统计选票时进行更新。
Check back and follow along as results start coming in on election night — these graphics will update as votes are counted.
随着选区向民主党或共和党倾斜，选民的党派转变也可能会影响众议院政治权力的分配。
The partisan shifts by voters will also likely affect the distribution of political power in the House, as districts either move toward Democrats or Republicans.
这张图表将在统计更多竞选结果时不断完善，它显示了与现在相比，2024年以共和党或民主党优势票数投票的选区数量。例如，如果民主党度过了一个不错的夜晚，更多的红色选区将转为蓝色。
This chart, which will fill in as more races are counted, shows the numbers of districts that voted with a Republican or Democratic margin in 2024 compared with now. If the Democrats have a good night, for example, more red districts will shift blue.
关于数据：“转变”将每个选区2026年众议院竞选中的共和党得票率减去民主党得票率的差额，与同一选区2024年总统选举的得票率差额进行比较，两者均占总投票数的比例。2024年总统选举结果来自美联社，并已针对当前的选区边界进行了重新计算。选票上没有同时出现民主党和共和党候选人的选区不包括在内。
About the data: Shift compares the Republican-minus-Democratic margin in each district’s 2026 House race with the 2024 presidential margin in the same district, both as a share of all votes cast. The 2024 presidential results are from the Associated Press and have been recalculated for current district lines. Districts without both a Democrat and a Republican on the ballot are not included.
