Grammatically, see post #2.
Lexically, I don't like the word "политика" at all.
Even though the word becomes more and more often used here, it is originally an adopted word meaning "politics", not "policy". But regardless of the fact that it's now rapidly enlarging its scope and becomes more and more stuffed with other English meanings, I still frown upon it.

I'd say:
