I don't really believe that egg prices could have made that big a difference. It was an easy thing for media reports to grab onto, but overall inflation was just not that high. I don't see people getting that bent out of shape over it.

It seems more likely that it made an easy thing to tell pollsters, rather than admit their real reasons. Exactly what those real reasons are, I have only dark suspicions, without evidence.
