I think democrats are taking the vaccine because Trump said to. Deep down they know he gets things done, and they know he doesn’t lie as much as their favorite talking heads say. The combination of the major lefty voices saying “take it” and Trump urging his supporters to take was enough for them.
We don’t just follow the mob blindly.
Not saying that he was orchestrating a depopulation event, just that there was no upside to dissuading people from taking it. They get what they want and are forced to remember that Trump made it happen. We don’t take it and are healthier for it.
