My conspiracy minded SyFy answer - Trump/Putin has some really, really bad dirt/threats against them. Then again, I'm beginning to think that is the answer. I hate to use the Hitler card, but I will - one reason Hitler (and Stalin and Mao and any mob boss) got away with it was to go after not merely the dissenters but their families as well. How else to explain how people that supposedly had some semblance of decency are staying quiet? I'm not just talking about McCarthy, et al, but also the ones who did resign or got fired. Their silence is deafening.
