今天是美国大选的日子，尘埃落定。总结了几个相关词汇，看看你知道几个。
1. neck and neck 并驾齐驱，不相上下；close race 势均力敌
2. edge ahead 领先
3. battleground state 战场州；swing state 摇摆州
In U.S. politics, a battleground state is a state where the political race between a Republican and Democrat, usually presidential candidates, is extremely close. Due to the way that presidential elections are run in the United States, the popular vote is not as important as the the individual tally of the states. This allows campaigns to pursue a state-by-state strategy in order to win an election, which makes those states where the race is close very important. （来源：http://www.wisegeek.org/what-is-a-battleground-state.htm）
4. electoral vote 选举人团的选票；electoral college选举人团；elector 选举人
选举人团(electoral college)又称选举团或总统选举团，是美国特有的一种选举方式。根据美国宪法，美国总统由各州议会选出的选举人团选举，选举人受选民委托到首都华盛顿投票，但投票意向由选民事先决定，选举人团投票表决只是例行公事。各州选举人票多寡取决于各州的人口。美国绝大多数州和首都实行"胜者全得（winner-take all）"制度，即在一州或首都获得选民票最多者获得该州或首都所有选举人票。赢得270张或以上选举人票的总统候选人即获得选举胜利。(来源：360百科)

6. congressional district method 国会选区法
7. beat sb 打败某人；win sth 赢了某事
