Barack Obama has now agreed to take part in three presidential debates with John McCain.
His aides are suggesting these are the only debates he will take part in, despite his earlier intent to appear at a series of town hall meetings with McCain.
All three debates will take place in the weeks just after the Democratic and Republican National Conventions.
The first debate is September 26th. The other two are scheduled for October.
A Vice Presidential debate is also planned at the beginning of October.
