竞争激烈、耗资巨大的美国国会初选星期二决胜负 Competitive, Expensive US Political Primary Races to be Decided Tuesday
美国5个州的选民前往投票站，选出11月举行的国会中期选举的候选人。
在美国西南部的亚利桑纳州，预计资深参议员麦凯恩在共和党初选中会轻易击败前众议员海沃思。最近的民意调查结果显示，2008年的共和党总统候选人麦凯恩以两位数字的优势领先于他的对手。
麦凯恩耗费了2千万美元用于这次竞选，相比之下，海沃思花了大约3百万美元。
在（东南部）佛罗里达州备受关注的一次角逐中，选民将选择一位民主党参议员候选人。众议员米克的竞争对手是房地产投资家格林。这位亿万富翁拿出了自己的数百万美元用来竞选。
初选的胜出者将同共和党候选人鲁比奥以及以无党派身份参选的现任州长克里斯特角逐参议员的席位。
Voters are going to the polls in five U.S. states to determine candidates for the general election in November.
In (the southwestern state of) Arizona, veteran U.S. Senator John McCain is expected to easily defeat former U.S. Representative J.D. Hayworth in a Republican Party primary. Recent public opinion polls indicate that McCain, his party's 2008 presidential candidate, holds a double-digit lead over his challenger.
McCain has spent $20 million on the campaign, compared to about $3 million for Hayworth.
In (the southeastern state of) Florida, voters will choose a Democratic candidate for the U.S. Senate in another closely watched race. U.S. Representative Kendrick Meek is facing billionaire real estate investor Jeff Greene, who spent millions of his own money on the race.
The winner will face Republican candidate Marco Rubio and current Governor Charlie Crist, who is running as an independent.
