“No matter how one looks at the data- by relying on the findings of economists, by looking at state level or looking a federal data, and no matter which economic measure one looks at, the answer is the same: Democratic policies are performing better. And not just a little better- drastically better.

The success of the Democratic states seems to play out across the board, even beyond the economic realm, as is evidenced by the consistently stronger performance of the Democratic states in terms of standard of living. In fact, even lifespans differ dramatically between red and blue states.”
