Kagan has a quintessential Upper West Side liberal pedigree, and within her writings you can pick out some hints of that – working for Liz Holtzman for Congress in 1980, her article on “Presidential Administration”, her opposition to don’t ask don’t tell, her college thesis on the rise of socialism (which should in no way be construed as anything but an academic review of the subject, actually). There are also warning signs, such as her writings on the First Amendment, her diversity record at Harvard law, her support of expansive executive power in the war on terror as Solicitor General and in her previous confirmation hearing.
