nested reference

My data structure is this:

Candidate content type: can have 3 different positions:

• president => no relationship
• senators => reference to a circumscription node
• representative => reference to a district

Circumscription content type: had a field referencing one or more district nodes.

District content type: had a field referencing one or more localities

What I'm trying to archive:

A view where I get all relevant candidates with locality title as filter, so it shows:

• All candidates to the president position
• All candidates to the senator position witch they circumscription includes districts witch include the filtering locality
• All candidates to the representative position witch they district include the filtering locality

I have tried many many ways using view references. But not luck. Please guide me into!
