　　The curtain on the 2008 US presidential election finally rose last month as John McCain and Barack Obama were formally nominated(提名)as candidates of the two major parties．This may be one of the hardest decisions voters have to make between two appealing candidates．

　　The big question for voters, as they face both an economic downturn and international threats, is：who will they elect?A young first-term senator promising change and new ideas, or a longtime senator with strong military experience and a reputation as a maverick(特立独行的人)?

　　American voters have never seen a candidate quite like Obama．He has a white mother from the US and a black father from Kenya who left the family when Obama was very young．He spent part of his youth in Indonesia．

　　His supporters say Obama’s childhood gives him the advantage to repair the recent damage done to America’s image abroad．His opponents focus on his inexperience, noting he hasn’t finished his first term in the Senate．

　　However, McCain has a very different life story．He grew up in a Navy family and was a pilot during the Vietnam War in the 1960s．When Obama was in kindergarten in Indonesia, McCain’s plane was shot down over Vietnam and he became a prisoner of war, where he was held for five years unless he disowned America, but he refused．

　　So in the end, the election may hinge on(以…为转移)several factors that are hard to judge：Will Obama’s race matter to a significant number of voters?Will working-class whites who tended to support his primary opponent, Hillary Clinton, vote for Obama?And perhaps most important of all, will swing(摇摆)voters be more drawn to Obama’s vision(远景规划)or to McCain’s experience?

　　Whatever happens, one thing is clear：Whoever walks into the White House on January 20, 2009, will find enormous challenges waiting for him in the Oval Office(美国总统办公室), both at home and abroad．
