What the Evidence Shows
The claim that "blue states generate 80% of the US income" is broadly supported by economic data showing that states which typically vote Democratic (blue states) contribute a majority share of the nation's GDP and federal tax revenue. However, the exact percentage varies depending on the metrics used (GDP, federal revenue, median income) and the geographic units considered (states vs. Counties).
According to USAFacts data, the four most populous states, California, Texas, New York, and Florida, contributed over half of federal revenue in 2023, with California and New York being blue states contributing significantly.usafacts.orgusafacts.orgWhich states contribute the most and least to federal revenue?

In summary, while "80%" is a reasonable approximation cited in some discussions, it should be understood as an estimate reflecting the concentration of economic activity and tax contributions in blue states rather than an exact figure. The claim is mostly true but simplified.
