Obama takes White House battle to rival's home turf

Barack Obama is using his record levels of fundraising and grassroots organisation to take the fight to his Republican rival John McCain’s home turf in the final week of the race for the White House, US political pundits said today.

Both presidential candidates held simultaneous rallies in Pennsylvania today, but Obama campaign aides said it was the only traditionally Democratic-leaning state the Illinois senator planned to visit before November 4.
