Washington (CNN) - The Obama campaign has bought an additional six million dollars of ad time in seven key swing states, a source tracking ad buys told CNN.
The re-election campaign in August reserved $32.5 million for broadcast and local cable commercials to air beginning Oct. 2 and going through Election Day in nine swing states but has added to that total since then. That was part of its unprecedented $77 million general election ad buy that began in August in Colorado, Florida, Iowa, Nevada, New Hampshire, North Carolina and Virginia running through Election Day.

Between Oct. 1 and this Sunday Obama's campaign will have spent at least $49 million while Romney's campaign will have bought almost $40 million in ad time.
Below are the details of the additional $6.24 million the Obama campaign has bought:
