A soft spot for Grandmas...

For three years, Rutgers tried to convince Obama to give a commencement address at its university, deluging him with petitions by mail, Twitter, Facebook, and YouTube.

But ultimately, the secret weapon for the New Brunswick, New Jersey, school ended up being a 70-year-old grandmother from the Jersey Shore.

Dianne Totten swayed the president with three candid letters, written on a basic form at WhiteHouse.gov. She wrote the letters on behalf of her grandson, outgoing Rutgers student body president Matthew Panconi — and helped persuade Obama to become the first sitting president in Rutgers' 250-year history to give the address.
