More Clinton donors shifting to Obama
Campaign finance records released this week show that a growing number of Clinton's early supporters migrated to Obama in March, after he achieved 11 straight victories. Of those who had previously made maximum contributions to Clinton, 73 wrote their first checks to Obama in March. The reverse was not true: Of those who had made large contributions to Obama last year, none wrote checks to Clinton in March.
(And this is through March, so, you have to figure there have been more.)
