WASHINGTON, DEC 14: The contest between Democrat First Lady Hillary Rodham Clinton and Republican Rick Lazio for the New York seat was the most expensive Senate race in American history. Figures released by the Federal Election Commission show that Lazio spent $39.6 million on his campaign to Clinton’s $29 million. The Republican has also set another record becoming the first losing candidate in a Senate race to have spent such a large amount. The previous record-holder was California millionaire Michael Huffington, who spent $29.4 million and lost to Democratic incumbent senator Dianne Feinstein, whose campaign cost much less.
