FARMINGTON HILLS, Mich. (AP) — CNN has called off a GOP presidential debate scheduled for March 1 in Georgia after Mitt Romney and Ron Paul said they would not attend.
Rick Santorum's campaign had signaled that he was unlikely to attend as well.
Newt Gingrich and the other three Republican candidates are scheduled to debate Feb. 22 in Mesa, Ariz.
Arizona and Michigan hold primaries on Feb. 28.
Romney's campaign noted Thursday that its candidate already has been in 20 debates.
