Here's a chart of coal mining employment, in this Huffington Post article of two days ago:
(Update: The Huffington Post removed this plot (without saying so), but it appears in this document from the Center for American Progress.)
Notice the caption, and the orange part of the line that signifies Obama's presidency.
Except this chart is wrong. The orange part is all wrong.
The chart says the data are from FRED, the database from the Federal Reserve of St Louis. But here are the actual data from FRED:
Notice the difference after 2012.
In fact, about 33,000 coal mining jobs have been lost under Obama. No comment now on the merits of that, just that the Center for American Progress seems clearly to have altered the data to be pro-Obama.
ThinkProgress and ClimateProgress are under the umbrella of the Center for Amerian Progress. Recall, they're the ones who won't tell you who funds them. Their president used to be John Podesta, who was Deputy Chief of Staff for Bill Clinton and is now Chairman of the 2016 Hillary Clinton presidential campaign. Maybe publishing bad data is their way of helping her get elected.
You might want to start checking whatever data they present.
Update 4:00 pm - The Huffington Post removed the chart. (I had emailed the author.)
