The "Publix" mood refers to a survey conducted by the grocery chain Publix regarding shopping trends and consumer sentiment, but it does not directly correlate to shifts in political power or the formation of majority parties in the House of Representatives.
However, if you are asking about the years in which significant changes in party majority occurred in the House of Representatives, two notable years are 2010 and 2018. In 2010, the Republican Party gained a substantial majority in the House during the midterm elections, while in 2018, the Democratic Party regained control of the House.
If you meant something different by "Publix mood," please provide more context, and I'll be happy to assist!
