The US arms industry is backing Hillary Clinton for President and has all but abandoned its traditional allies in the Republican party. Mrs Clinton has also emerged as Wall Street's favourite. Investment bankers have opened their wallets in unprecedented numbers for the New York senator over the past three months and, in the process, dumped their earlier favourite, Barack Obama. An analysis of campaign contributions shows senior defence industry employees are pouring money into her war chest in the belief that their generosity will be repaid many times over with future defence contracts. Employees of the top five US arms manufacturers - Lockheed Martin, Boeing, Northrop-Grumman, General Dynamics and Raytheon - gave Democratic presidential candidates $103,900, with only $86,800 going to the Republicans. The contributions clearly suggest the arms industry has reached the conclusion that Democratic prospects for 2008 are very good indeed," said Thomas Edsall, an academic at Columbia University in New York. Republican administrations are by tradition much stronger supporters of US armaments programmes and Pentagon spending plans than Democratic governments. Relations between the arms industry and Bill Clinton soured when he slimmed down the military after the end of the Cold War. His wife, however, has been careful not to make the same mistake. After her election to the Senate, she became the first New York senator on the armed services committee, where she revealed her hawkish tendencies by supporting the invasion of Iraq. Her position on Iran is among the most warlike of all the candidates - Democrat or Republican. While on the armed services committee, Mrs Clinton has befriended key generals and has won the endorsement of General Wesley Clarke, who ran Nato's war in Kosovo. The arms industry has duly taken note.
