I dont think its about voting. The whole system is corrupt there due to the people who have power. And if west lets them legally spend their money its going to be transparent to the people in Russia. Which might push them towards some action.

Btw west itself is not Liberal Democrat. Checkout Russian Liberal democrat Vladimir Zhirinovsky you'll see how different Russia is from West. I feel like you expect a western solution to a Russian problem. Im dont expect everyone agree with me, but to me it seems like this problem needs some extreme (not normal) approach
