The Ex-Mitt Club

David Bernstein finds that just a quarter of those who gave large amounts to Mitt Romney’s presidential campaign four years ago have contributed again this year.

“Even Romney’s earliest supporters are, for the most part, sitting on the sidelines. Just 30 percent of big donors who gave in the first three months of 2007 have given this year. Of those who gave in the very first week last time, the return rate is 40 percent — still well under half.”
