since his grandfather and father were both muslims, doesn't that make him "mulsim" by muslim protocol?

No. Barack Obama is not a Muslim.

Here's a profile on Obama that details his life (so far):

He is a liberal (politically and religionally).
But I won't fault the guy and his wife for "stepping up".
Sure, what they did with the HIV test is a bit of grand-standing, but
parts of Africa are in such a mess with HIV that Obama and wife have
dun' good this time. (IMHO)
He used a bit of celebrity to get people to take care of themselves
(and spouses and children).
