The media won't be reporting any results until the polls close. That's because they don't want to report that Debra is in the runoff or is winning, and are still trying to sway the last minute undecideds to rick and bailout. This is the reason why there haven't been any exit poll results reported for early voting.
edit: Surely when results are reported, a statement to the effect of "our exit polls of early voting had confirmed last week that Medina will make the runoff (or win outright)" will be included.
