McCain—Scared of Obama—or Scared of Palin’s big mouth?

Future Leaders of this country...we are doomed
Future Leaders of this country...we are doomed

So John McCain wants to cancel the debate for tonight and postpone it until the day the VP debate is scheduled.

so the question is:

Is McCain afraid of Obama’s much better ability to speak and convince (teleprompter or not, he sounds a hell of alot better than McCain) ?

OR

Is McCain afraid to let Palin open her big mouth and embarrass him again?

comment and tell me what you think!
