Perry,
The question could also be asked why McCain did not agree to Obamas debate proposal. Why aren't you asking that question?

This is nothing new - campaigns these days spend all kinds of time figuring out how to set up a debate format to give their candidate the edge. Obamas guys have to same right to do what McCains people are doing.
