Cmon the meme is kinda funny.
The rightist promoters of the NPC meme would agree with that statement -- but they would say that it's because most are just acting as ideologically/memetically programmed automatons. Crucial to understanding this meme is that its promoters see "libs" not as literal bots, but as humans-with-bot-thinking, who have grown up on a diet of platitudes and mantras without deep analysis.
On the contrary, the left/libs/progressives (whatever you want to call them) on Twitter have had a habit of actually doing what you're saying, when they pull out the "oh look another Russian bot" troll. That meme actually asserts that the number of actual conservatives/right-wingers is literally small and being amplified by actual programmed chatbots.
High turnout tends to favor Democrats, so they are less motivated to engage in this particular kind of election fraud. I don't think that makes them smarter or dumber.
