McCain seeks advantage

US Republican presidential candidate John McCain is to campaign in Colorado, as he seeks to take advantage of his rival\'s brief absence from the trail.
Barack Obama has halted campaigning to see his ill grandmother in Hawaii.
His wife, Michelle will replace him at an Ohio rally.
Some polls have shown the Democrat\'s lead narrowing in key battleground states.
Meanwhile, McCain\'s running mate, Sarah Palin, is to give a deposition to a second inquiry into her alleged abuse of power as governor of Alaska.
It comes as two leading Republicans announced they had chosen to endorse Obama rather than their party\'s own candidate.
They are former Bush White House press secretary Scott McClellan and Republican Minnesota Governor Arne Carlson.
There are fears that the news, which comes only days after former Secretary of State Colin Powell gave his endorsement to the Democratic candidate, may dent McCain\'s efforts to seize back the initiative.
