A Florida urologist is so upset with the new health care bill that he's posted a sign at his practice warning President Barack Obama's supporters to find another doctor.

The notice on Dr. Jack Cassell's Mount Dora office says: "If you voted for Obama, seek urologic care elsewhere."

Cassell tells the Orlando Sentinel he's not turning away patients, because that would be unethical. But the 56-year-old says it's OK with him if any Obama supporters chose not to see him after reading the sign.

The urologist also keeps Republican materials in the waiting room.

Experts say Cassell is toeing a thin line between right and wrong.

Doctors can't legally discriminate based on a patient's race, gender or religion, but civil rights laws don't explicitly protect political opinions.
