Rachel Maddow has shown charts, the difference, Reagan, GHB & GWB added public sector jobs, Obama has cut public sector jobs.
She said the cuts added another 1% to the unemployment.
Remember, under GWB we added Homeland Security, The Patriot Act, how many employed by them, just to name a few.
Here, I found an article to shed light on this subject.
But there is one area of job creation where President Bush clearly outshines President Obama: the public sector. Public sector employment is now down 608,000 workers since January 2009, a 2.7 percent decline. At the same point in President Bush’s term, public sector employment was up 3.7 percent. If, over the past 40 months, public sector employment had grown at the same pace as it did in President Bush’s first term, there would be 1.4 million additional people at work right now. That’d be enough to bring the unemployment rate down by nearly a full percentage point.
