It's not fear that drives trump loyalty...
Whatever word you want to use for it — fascism, authoritarianism, pick your poison — the grim reality is that Republicans, both politicians and voters, appear to be all in on this project. It's painful to admit this, but Republicans have flat-out rejected democracy. As a group, they are pushing towards replacing democracy with a system where a powerful minority holds disproportionate and borderline tyrannical control over government and blocks the majority of Americans from having meaningful say over the direction of the country.
Republicans are not cowering in fear of Trump. On the contrary, they are exalting in his shamelessness. Watching Republicans at impeachment hearings, where they performed outrage for the cameras, lied with obvious glee and gloried in sharing conspiracy theories, it did not appear that they were intimidated by their president or anyone else.
No, Republicans clearly feel empowered by Trump. He frees them to reveal their darkest desire — which is to end democracy as we know it, and to cut any corners or break any laws necessary to get the job done.
And the Republican voter base is right there along with the politicians. A new Washington Post/ABC poll found that, despite recent hearings that made it almost comically obvious how guilty Trump is, Republican voters are standing by their man. When asked if Trump should be impeached and removed from office, 86% of self-identified Republicans said no. In fact, in the face of mounting evidence of Trump's guilt, Republicans are digging in even more. Fewer Republican voters support impeachment now than a similar poll showed in October.
It's easy to write this off as pure tribalism, and there is no doubt that's a big factor. But that can't account for the entire phenomenon, especially since Democrats have shown no interest in pursuing evidence that Vice President Mike Pence was involved in the crime (though it does appear he is implicated), which would mean that dumping Trump wouldn't actually cost Republicans the White House.
No, the darker truth is that Republican voters, like Republican politicians, see clearly what Trump did — use the power of his office in an overt attempt to cheat in the 2020 election — and they love it. Like their leaders, Republican voters are feeling done with democracy and eager to follow Trump into a new world, where the majority of Americans who vote for Democrats are kept out of power, by any means necessary.
