Columbus, Ohio (AP) -- Barack Obama won over Ohio's key swing groups on his way to capturing the all-important battleground state.
Independents, moderates and women in Ohio all threw their support behind Obama.
The Democrat also won across all age groups except those 65 and older.
Obama won by a wide margin among women voters who four years ago split evenly between the two parties.
Nearly all black voters backed Obama while white voters slightly favored john McCain.
Voters who say the economy is the top issue overwhelmingly backed Obama as did voters worried about health care and the war in Iraq.
