I think the Tea Party is only tenuously connected to Trump. A lot of his policies involve a lot of government spending and federal overreach, and his policies are often opposed by the Freedom caucus. Historically, anyway, right wing populism tends to follow the collapse of the radical left and becomes a dark mirror of those very same movements, attempting to absorb their energies (Steve Bannon’s Leninism, Trump’s workerism). The tea party was, conversely, the last cry of reaganism and the dream of mixing traditional life with libertarian economics, which was flawed from the start as it was that very same deregulation which led to our contemporary technologically inflected society where all social norms are broken for the sake of profit. So the tea party was not the legitimate bearer of world history.
