If a Jew were elected president of the United States, would he/she be required to put a mezuzah on all of the doors of the White House? I can think of many arguments for each side.
The house does not belong to the president. Nonetheless, we do require placing mezuzot on rented dwellings.
The White House may not be considered a dwelling due its public use. Still, there is a section of the White House called the "Executive Residence" which is where the president and first family live. Perhaps this section needs mezuzot and the rest of the White House does not. On the other hand, even the Executive Residence is still somewhat of a public space, with many rooms the first family likely never uses, rooms for hosting state events, rooms used by White House employees, etc. But perhaps these are akin to guest rooms/entertaining rooms in a normal house.
It seems somewhat strange to affix mezuzot to some doors in the White House and not others. After all, the halakha is that every room in a house must have a mezuzah. But since the rest of the house is a public space, perhaps this is more akin to an apartment building where the Jewish resident is only responsible for placing mezuzot on the space he/she occupies.
So to which doors (if any) would a Jewish president need to attach a mezuzah?
