The Debate is On!

— -- The debate is on!

ABC News' George Stephanopoulos confirmed that Sen. John McCain will be attending the first presidential debate tonight in Mississippi.

"Optimistic that there has been significant progress toward a bipartisan agreement," the McCain campaign said in a statement they are "resuming all activities and the Senator will travel to the debate this afternoon."

McCain announced on Wednesday that he was suspending all campaign activity to head to Washington and work towards a resolution on the bailout plan.
