WINTER PARK, Fla. (AP) - President Barack Obama has a simple wish for his upcoming 51st birthday: Florida's 29 electoral votes.

Supporters in suburban Orlando sang "Happy Birthday" to Obama during a campaign rally on Thursday, an early nod to his birthday on Saturday. The president says his birthday wishes probably involve "electoral votes," adding, "Winning Florida wouldn't be a bad birthday present."

Obama is expected to keep a low profile on his birthday, spending the weekend at Camp David, the private presidential retreat in Maryland's Catoctin (kuh-TAHK'-tin) Mountains.

But presidential politics will get the birthday treatment. The president is holding a birthday-themed fundraiser at his family home on Chicago's South Side on Aug. 12.
