Washington D.C. is filled with research organizations -- so-called "think tanks" -- that span the political spectrum and range from neutral to strongly ideological. Some specialize in specific topic areas, such as in social problems, economics or defense. All provide opinions on policy and aspects of governance. These think tanks also house officials from previous administrations who often return to government when their political party comes back in power. VOA's Jeffrey Young has more on how these organizations fit into the public policy process.
