We welcome Dan Hopkins, a professor in Georgetown’s Department of Government. He will be guest-blogging for the next two weeks or so, talking about Katrina, race and ethnic politics, the Tea Party, and whatever else catches his fancy. I “posted previously”:https://themonkeycage.org/2008/07/whither_the_wilder_effect.html on Dan’s research about the “Bradley effect.” You can be more about his research “here”:http://people.iq.harvard.edu/~dhopkins/. Welcome, Dan!
