Timothy Geithner (R-I)
Yesterday, Timothy Geithner was officially announced as President-Elect Barack Obama's Treasury Secretary. You might know that Mr. Geithner worked at Treasury at the end of the Reagan Administration, and eventually served right under Bob Rubin and Larry Summers during the Clinton years. You probably know that he's been the President of the Federal Reserve Bank of New York since 2003. What you might not yet have heard is that Geithner is a former Republican (and now an independent.)
Not much has been made of this, which I take as being a very good sign. The overwhelming majority of people just don't care about a person's political pedigree, so long as they're confident it won't interfere with his or her ability to do what's right. In this case, there was zero concern among Democrats that Obama tapped a non-Democrat to play such an enormous role in the administration.
