alt Hacker NewsI've lived in over a dozen states and I've never heard either called anything other than EYE-(ran/raq) in conversation.
The extremely, I mean extremely rare occasion when someone pronounces it differently on TV, it's almost like they get side-eyed by other people as trying to "talk fancy".
Well, I've lived in four states in the last 20 years.
Anecdotally, the pronunciation popularity has split neatly along statewide-prominent political lines. For my four example states, three were correct/respectful, and one wrong/disrespectful.
Correct pronunciation has also had an inverse correlation with the rates of active/former military employment, which might be more directly indicative. And a positive correlation with education levels. So the answer is in there somewhere, I suspect.
National TV "news" programming might have a style guide which dictates pandering to the audience by speaking in real american, no matter how well-educated the hosts might be.
