　　Ohio, Pennsylvania may hold key to White House
　　With Election Day only some 24 hours away, both U.S. presidential campaigns are focusing on Ohio and Pennsylvania as the pivotal states.
　　Democratic presidential nominee Barack Obama and Republican vice presidential choice Sarah Palin crisscrossed Ohio on Sunday, while Republican candidate John McCain returned to Pennsylvania.
　　The Washington Post said both campaigns expect a close finish in Ohio, something of a paradox in a struggling state in a year in which the poor economy is driving support for Obama and other Democrats.
　　Ohio lost 300,000 manufacturing jobs this decade and its median income has dropped by 3 percent, yet polls show Obama with no more than a narrow lead in a state that John F. Kerry lost to George W. Bush by two points in the last presidential election.
　　The Wall Street Journal quoted McCain campaign manager Rick Davis as saying that Pennsylvania, won by Kerry in 2004, will be the most important state to watch Tuesday.
