New polling may explain why Barack Obama is concentrating on a slew of traditionally Republican states with less than a week until Election Day.
He wants to guarantee victory, and win by a landslide if possible.
The AP-GfK polls show Obama leading John McCain in four states President Bush won in 2004. Obama is essentially tied with McCain in two other so-called "red" states.
According to these snapshots, Obama has solid leads in six key states: Colorado, Nevada, New Hampshire, Ohio, Pennsylvania and Virginia.
The candidates are tied in North Carolina and Florida.
A couple of factors could be in McCain's favor. Some voters remain open to changing their minds, from as low as 4 percent in Nevada to 14 percent in New Hampshire. And the impact of race is hard to measure as Obama seeks to become the nation's first black president.
