For those who want to peek behind the curtain of the White House--to see how decisions get made--then there is no better time than when a President releases records from his administration. Five years ago the Reagan Library released the Alito memos, which detailed the strategy to create the signing statement, among other things.
Now that President Obama has nominated Solicitor General Elena Kagan to take over the Supreme Court seat vacated by retiring Justice Stevens, and since Kagan previously worked as a domestic policy adviser in the Clinton administration, the Clinton Library has dumped a number of her memos which are fascinating. So if the "tic toc" of politics is your thing, then you have to visit these documents and read through them.
