Is there a deadline ??

Sooner or later, there will be, as individual states will require candidates to be on the ballot some XX days before the primary/caucus.

No, not really a deadline... but definitely limited attention span. In America it's about 5 nanoseconds before reruns get stale. I expect Fred Thompson knows this.
