Guess which states depend on federal tax dollars the most? If you said "Republican-controlled Southern and Midwestern states" then you get the brass ring.
That's Mississippi there at the most dependent state in the nation, 42.9% of the state's revenue comes from Washington DC. Meanwhile, large blue states like California and New York? Near the bottom.
In fact with the exceptions of Louisiana at number 2 (who just elected a Democrat in late November) and #6 Montana (Democrat Steve Bullock) all the top ten moocher states have GOP governors. Fiscal conservative John Kasich, running for the 2016 White House on a federal balanced budget? His own state is #19 on the list, getting more than a third of all revenue from the Feds.
Funny how that works.
