The guest list was top secret for President Obama‘s $30,000-a-head Harlem fund-raiser the other night. But sources tell us that those who helped raise more than $1 million for Obama included financier Orin Kramer of Boston Provident, New York State Democratic Committee Chairman Jay Jacobs with wife Mindy, Chelsea Piers president Tom Bernstein, and Evercore Partners’ Ralph Schlosstein and wife Jane Hartley. Also there: White House adviser Valerie Jarrett and Rep. Charlie Rangel, who did not have to pay.
