From the SOS regarding a runoff:

If there is a Primary Runoff Election:
The 2014 Primary Runoff Election will be held on June 24, 2014 (Miss. Code Ann §23-15-305)
Polls are open from 7:00 am to 7:00 pm.
Citizens must have been registered for the June 3, 2014 Primary Election to be eligible
to vote in the June 24, 2014 Primary Runoff Election. If an eligible voter did not participate
in the June 3rd Primary Election, the voter may vote in either the Democratic or Republican
Primary Runoff. The State of Mississippi does not allow “crossover” voting. Meaning,
if a voter cast a ballot in the Democratic Primary, he/she must cast a ballot in the Democratic
Primary Runoff. If a voter cast a ballot in the Republican Primary, he/she must cast a ballot
in the Republican Primary Runoff. (Miss. Code Ann §23-15-575)Uniformed and Overseas ballots
have been transmitted in accordance with State and Federal law.
Does a person have to be registered as an R to be eligible to vote in the R primary in MS? That quote seems to be saying that a voter who didn’t vote in the initial primary can vote in either a R or D run-off. But it depends on what “eligible voter” means. If a person is registered as a democrat, are they an “eligible voter” in the R primary and/or runoff?
By saying there is no cross-over voting it seems like this is saying that MS is NOT an open primary state so an “eligible voter” would be one who was registered to vote in the primary process for a given party.
IOW, that statement is as clear as mud.
