I just ran across a link to an article by Thomas Sowell, author of the book Conflict of Visions. I read the book probably ten to fifteen years ago; It is a powerful articulation of the conservative political philosophy and its origins in America. In the article he addresses his concerns about judicial appointments by a president Obama. Check it out.
You might also be interested in taking a survey to compare your values with Obama's stated positions. http://www.barackobamatest.com/?fuseaction=home.options
