Biden and Palin are set to debate October 2.

(CNN) - McCain supporter Sen. Lindsey Graham tells CNN the McCain campaign is proposing to the Presidential Debate Commission and the Obama camp that if there's no bailout deal by Friday, the first presidential debate should take the place of the VP debate, currently scheduled for next Thursday, October 2 in St. Louis.

In this scenario, the vice presidential debate between Joe Biden and Sarah Palin would be rescheduled for a date yet to be determined, and take place in Oxford, Mississippi, currently slated to be the site of the first presidential faceoff this Friday.

Watch: Obama camp pushes for debate

Graham says the McCain camp is well aware of the position of the Obama campaign and the debate commission that the debate should go on as planned - but both he and another senior McCain adviser insist the Republican nominee will not go to the debate Friday if there's no deal on the bailout.
