If I said he has actually “declined,” then I misspoke. Sorry. He has said he is thinking about not doing any more debates.
Rush discussed this extensively on his show last week (actually saying he was okay with Perry cutting his losses, taking whatever criticism comes from withdrawing, and trying to get into situations where he could effectively get his message out).
IMHO opinion, Perry is thinking of passing some debates, as it is a weak point for him and takes away from campaigning. Cain is thinking of passing campaign appearances because its draining his money.
Beyond that, Mr Cain realizes he is one step away from major scrutiny if he keeps providing sound bytes.
Believe me, the opponents have a ton of unabashed sound bytes.
