The story is here.
Just how bad was the winter? Out of 69 winters in the post-war 2015 ranked 22nd worst for heating degree days, and all Obama could manage is 0.1% nominal growth over the prior quarter, $6.3 billion. But 1959 came in 21st and somehow America under Eisenhower could manage 2.0% nominal growth q/q in winter. And 1964 ranked 23rd and somehow America managed 3.1% nominal growth under JFK in winter.
The winter of 2014 ranked 10th worst, and Obama gave us a pathetic nominal growth of -0.2%, yet in 1977 which ranked 9th worst winter in the post-war Jimmy Carter, Jimmy Carter!, gave us +2.6% nominal growth. The 12th worst winter was in 1962 and again JFK gave us 3.4% nominal growth.
The story is the same for 2010 and 2011, 33rd and 35th worst winters, which is to say, not very bad. These winters appear in the warmer half of the record. Obama gave us just 0.8% and 0.1% respectively, flanked by winters of like severity in 1972, 1951 and 1957 posting nominal growth of 3.4%, 6.3% and 2.2% respectively.
2013? Only the 42nd worst winter. But 1967 was worse and we got 2.4% nominal then, thanks to LBJ. Obama gave us 1.0%. And 1950? 43rd worst, but it clocked in with 3.7% nominal growth.
2012? The warmest winter in the record at 69th. So the weather argument should have meant economic growth had been absolutely stellar by comparison with everything going before it, right? Instead Obama gave us 1.1% nominal. Well, that IS Obama's best performance in winter, so maybe the heat helped a little. But 1990, which ranked 68th, witnessed 2.3% nominal growth under George H. W. Bush.
You see the pattern here? Obama "underperforms" everybody around him in similarly situated weather. But actually his numbers are so bad in winter it's like he's not even in the game.
Average Obama score in winter outside of recession: +0.5%.
Everybody else in the same boat: +3.1%.
