Mostly see a politician where stars are looked for? (11)
I believe the answer is:
observatory
'where stars are looked for?' is the definition.
(where stars can be observed)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for observatory that I've seen before include "E.g. Jodrell Bank" , "Astronomy centre" , "Building housing a large telescope" , "Building equipped to view the heavens" , "Building used for astronomy" .)
