The Democratic Dividend – The stock market prefers Democratic presidents to Republicans. Why? By Carol Vinzant Republicans are no doubt muttering that that’s just the stock market, not the whole economy. But real GDP growth follows the same pattern. Since 1930 (the first year decent data is available), GDP growth was 5.4 percent for Democratic presidents and 1.6 percent for Republicans.

Same pattern, perhaps, but the difference in GDP growth (More than a 3 fold difference) is even more striking that the difference in the growth of the Dow (12.3% for Democratic Presidents and 8% for replublican, only a 50% difference).
