Oh, and 4 of the 10 states with the highest percentage of the population receiving federal benefits are blue states.

A higher percentage of the population in Oregon, Illinois, New York, and Rhode Island receive welfare benefits than in the state of Texas.

But states like Illinois and New York have a huge wealth gap. They have a lot of poor people receiving benefits but they also have a disproportionate number of really wealthy people paying a lot of taxes.

So it's not a blue state sending money to a red state, it's a small minority of the population of the blue state that is insanely wealthy sending money to red states. Which is precisely how Democrats designed the federal budget, tax the wealthy at a higher rate and redistribute that money to the less wealthy.
