Word of something new from Vivisimo's Clusty.com this afternoon. The company has just launched a new "government tab" that allows you to search and cluster results from a variety of government info sources including FirstGov, MSN limited to the ".gov" domain, DefenseLink, political news from Reuters, the Associated Press, and CNN, and a number of prominent American think tanks, including RAND, The Brookings Institution, and The Cato Institute. An advanced search interface is available.
Also, Clusty continues to make search/cluster versions of key government reports and documents available. They're now providing a search/cluster version of the 2006 U.S. Budget.
Finally, Clusty now offers a shortcut to find info about members of the U.S. Congress. Enter a state name, postal abbreviation, or Zip Code in the search box and at the top of the page you'll find pictures, links to voting records, and email info.
