Even if you find a great job where you can focus on the "15%" there will always be other departments / managers / competitors, who doesn't play by your rules. You better get used to it and continue doing a good job & read the book "How to Win Friends & Influence People".

If I were you I would stay at least for one another year in my current position and quit first when I know how to handle politics.
