今天是美國大選的日子，塵埃落定。總結了幾個相關詞匯，看看你知道幾個。
1. neck and neck 并駕齊驅，不相上下；close race 勢均力敵
2. edge ahead 領先
3. battleground state 戰場州；swing state 搖擺州
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. （來源：http://www.wisegeek.org/what-is-a-battleground-state.htm）
4. electoral vote 選舉人團的選票；electoral college選舉人團；elector 選舉人
選舉人團(electoral college)又稱選舉團或總統選舉團，是美國特有的一種選舉方式。根據美國憲法，美國總統由各州議會選出的選舉人團選舉，選舉人受選民委托到首都華盛頓投票，但投票意向由選民事先決定，選舉人團投票表決只是例行公事。各州選舉人票多寡取決于各州的人口。美國絕大多數州和首都實行"勝者全得（winner-take all）"制度，即在一州或首都獲得選民票最多者獲得該州或首都所有選舉人票。贏得270張或以上選舉人票的總統候選人即獲得選舉勝利。(來源：360百科)
5. winner-take all 贏者通吃，勝者全拿
6. congressional district method 國會選區法
7. beat sb 打敗某人；win sth 贏了某事
