I start to get a bit worried

[merrily]

11. A Jew is running for President IS a bit unusual, though.

Not unique.



But, still unusual.

When JFK ran, the US was not verbally p.c. So, he got asked flat out if America should be worried that he would take marching orders from the Pope. Now, we're verbally p.c., but attitudes linger. So, now, no one is going to ask if Bibi is going to be the real President of America if Sanders is POTUS. But, there might be dog whistles.

I think that is what the OP may be getting at when she asks why Bernie is the only getting these questions when all the candidates have similar positions.

For example, in this land of immigrants, nothing is unique or even unusual about someone traveling to the homeland of a deceased parent and checking out traditions and such, as a way of somehow getting in touch with something. But, when that gets attention during a political campaign, it could be a dog whistle, from the opposition and/or media. Or not.
