>So the 4 biggest payers in 2018 were New York, New Jersey, Massachusets and Connecticut. Aren't these all "blue states"?

Yes, but my point is that those states are subsidizing almost the rest of the country, no matter who those other states voted for.

>The 4 biggest recipients are Alabama, Kentucky, Maryland, Virginia. Aren't those all "red states"?

No. Maryland is a very Democratic state, and Virginia is a swing state that has recently voted mostly Democratic, including for Hillary in 2016.
