The Center for American Progress was created in 2003 as a Democratic alternative to think tanks such as the Heritage Foundation and the American Enterprise Institute. In 2011, the "Washington Post's" Jason Horowitz described the Center for American Progress as "Washington’s leading liberal think tank," and "an incessant advocate for a broad progressive agenda and as such, a sharp thorn in President Obama’s left side. Horowitz further concluded that the Center, more broadly, had since become one of "Washington’s leading liberal think tanks."
