______________________________________.Jim Malone has report.吉姆·摩罗伦发回的报道Mitt Romney cruised to victory in Arizona and then held on for a narrow win in his home state of Michigan, defeating conservative challenger Rick Santorum. Romney was trailing in the polls in Michigan two weeks ago but he steadily eroded Santorum's lead with help from negative TV ads and a strong debate performance last week. Although he lost in Michigan, Santorum hopes his strong showing there will help him next week when ten states hold voting contests on March 6th, also known as Super Tuesday. Jim Malone, VOA News, Washington.米特·罗姆尼在亚利桑那州的竞选中轻松获胜，然后在他的家乡密歇根州又一次险胜，击败了保守党的竞争者里克?桑托姆。两星期前，罗姆尼在密歇根州的民意调查中落后于桑托姆，但是他凭借对手的负面电视广告和上周出色的辩论表现削弱了桑托姆的领先地位。虽然在密歇根州的预选中失败，但桑托姆希望他在密歇根的出色表现能有助于他在下周的3月6号，即所谓的超级星期二的竞选中获胜。届时，将有10个州进行投票竞选。吉姆·摩罗伦从华盛顿为您带来的VOA新闻报道。
