This may answer why .Bernie having this many votes despite being a Russian puppet is fkin disappointing.

Russia is 6th place as far as issues most people care about. While the top two issues are the issues Bernie Sanders mostly talk about . If you don't have a job or healthcare it's really hard to care about Russia spy games relatively speaking.
So more likely people don't care what Russia's preference is when it comes to who they decide to support . It's unimportant .
