11月1日和2日为美国总统选举最终投票日到来前最后一个周末。对于民主和共和党两党总统候选人贝拉克·奥巴马和约翰·麦凯恩,战前动员、互相攻讦、亲临战场州前线……各种竞选手段在最终攻坚时刻一个都不能少。截至2日的民调显示,奥巴马可能至少会获得290张选举人票,超过当选总统所需的270张。

最后动员
临近终点,动员必不可少。奥麦两人均在竞选活动中呼吁支持者踊跃投票。不同的是,奥巴马一方士气高昂,鼓励支持者乘“风”前进、一鼓作气。
麦凯恩一方则意在打气,告诉人们胜望犹存、不要气馁。
美国媒体10月31日公布的民意调查结果显示,奥巴马支持者情绪越发高涨,而麦凯恩拥趸则更加消沉。
优势明显
奥巴马的信心来自民调。美联社和雅虎新闻1日公布的联合民调结果显示,奥巴马以51％的支持率领先麦凯恩8个百分点。
不过,路透社等3家民调机构联合开展的调查结果显示,麦凯恩逐渐缩小差距。这份同样公布于1日的民调结果把奥巴马对麦凯恩的领先优势定在5％。
麦凯恩方面坚称,两人差距现阶段不过4％。这比民调通常误差率只多一点。
奥巴马1日在密苏里州竞选活动上被问及是否担心民调差距缩小。他回答：“我从未担心过民调,我应该为民调担心吗？”
今年全美共有30多个州开放了提前投票,调查显示,已经有24%的选民表示完成提前投票。据《华盛顿邮报》和美国广播公司（ABC）于当地时间2日共同公布的民调显示,在已提早投票的选民中,59%的人表示他们把票投给了民主党的奥巴马,而40%的人说他们投给了麦凯恩。在即将前往投票的选民中,53%表示支持奥巴马,44%称支持麦凯恩。
此外,在剩余的可能前往投票的选民中,93%表示他们已决定支持的对象,其中一半表示不会改变决定。另外7%选民尚未决定投票对象。　　
惊人票数
按照美国选举法,要当总统不是直接看民众投票的普选结果,而是全国选举人票数。美国50个州和哥伦比亚特区共有538张选举人票,选举人票数分配与每个州的人口多少挂钩,最多的加州达到了55张。由于美国48个州实行“赢该州普选便赢得该州选举人票”政策。按照目前民调数据,无论普选得票率,还是换算所得的选举人票数,奥巴马两项数据已超麦凯恩,特别是理论上获得的选举人票数,按照各民调换算,更是达到了290——333张,超当选总统所需要的270张（538张总票数一半）标准。
2000年总统大选,戈尔以48.32％的普选得票率超过了布什的47.99％；但戈尔只得到267张选举人票,布什却有271张,结果反是布什当总统。
