Trying to track down the 2012 GOP debate schedule can be a time-consuming experience. Some states, like Florida, have two Republican debates, while others, like Georgia, have only one. Some begin at 8:00 p.m. and some at 9:00 p.m., and some will have no set starting date at all until a week before the event itself.

To save time and keep informed, check out the list below. This is the most up-to-date and complete schedule available for the 2012 Republican primary debates, from the second debate this week in Jacksonville, Fla. to the final primary debate in Portland, Oreg. Times, participants and locations will be updated when the information becomes available.
