According to the US-based Center for Responsive Politics, spending on the election – for President and Congress, and including spending by outside groups as well as by the candidates and their political parties – is estimated to have exceeded $6 billion. That makes the 2012 US election the most expensive ever held.
根据美国响应政治中心（Center for Responsive Politics）的数据，此次选举的支出——包括总统选举和国会选举，包括外部集团支出和候选人及其政党支出——估计将超60亿美元。这使得2012年美国大选成为史上最贵大选。
