I looked and it seems like egg prices spiked the most in 6/7 of the swing states from 2022-2023:

The data source is a paywalled business insider article, but it's got an archive link
granted it's a website run by like 1 guy with a secondhand source (BI is citing an Instacart study) but if it's accurate it means that 3 of the top 10 states for egg prices are swing states (Nevada, Arizona, Georgia) , and if you look at inflation per dozen eggs per state Wisconsin, Michigan, and Pennsylvania are also in the top 10. All of those states also have low minimum wages (Arizona's an outlier at like 13 bucks but every other swing state, it's $10 or the federal minimum).
