Is Barack Obama's drinking "problem" hereditary?

The president was told by his doctors to “moderate” his alcohol intake.  This doesn’t mean Obama is an alcoholic but a glimpse at his father’s past should set off warming signals.

From Wikipedia :

The decline began after Tom Mboya’s assassination in 1969. Obama Sr. was fired from his job by Jomo Kenyatta, was blacklisted in Kenya, and began to drink . He had a serious car accident, spent almost a year in the hospital, and by the time he visited his son in Hawaii in late 1971, he already had a bad leg. (Dreams from My Father, pp. 64–71, 212-219). Obama Sr.’s life fell into drinking and poverty, from which he never recovered. His friend, Kenyan journalist Philip Ochieng, has described Obama Sr.’s difficult personality and drinking problems in the Kenya newspaper The Daily Nation.[17] Obama Sr. later lost both legs in another automobile collision, and subsequently lost his job. He died in 1982, at the age of 46, in a third car crash in Nairobi.

If diseases are hereditary, and alcoholism is a disease, perhaps it is time for Hussein the Usurper to quite drinking and smoking altogether?

God help us!
