I hear it from the few liberals in my life who think Russia has immense influence on Trump and the current state of our country is therefore Russia's fault. I hear it from people of many ideologies who push the "Zionist occupied government" rhetoric to avoid confronting our states track record of being a genocidal monster and our power over the Israeli state. Of course I also hear it from fascists who blame various minorities for their financial troubles. It's very common. I'd argue most politically aware Americans passively subscribe to one of these beliefs if not actively but this is just my subjective experience.
