Two small items in the New York Times from the Democratic Convention caught my eye. The first was that Rahm Emanuel, the Mayor of Chicago, is now leading a Democratic SuperPac, one of those new types of fund-raising organizations, trying to pry big dollars loose from liberal donors. Some of these donors have refrained out of principled opposition to SuperPacs. Others have more personal reasons. For example, George Soros has taken a pass because he could not get face time with President Obama. So it will be a tough sell.
