A major part of the reason for this is that the politicians (and more generally presidents, judges, prosecutors, police officers, lawyers, reporters, whistle blowers, various citizens, etc.) that had courage, ability and will to do what was genuinely, in depth right, has frequently been assassinated, attempted to be assassinated, or "reined in". Both prominent and less prominent have been targeted. For instance John F. Kennedy, Scalia ("wet works"...), Ronald Reagan (whom was shot a few months into his presidency), Seth Rich, Scalise, Clinton body list, etc. etc. etc. etc. And Epstein as well. And thus there are fewer and fewer and fewer people per generation that dare speak out or take action reg. what is genuinely right, resulting in or contributing to critical consequences such as the kind of Republicans you describe (which do not fit all Republicans). The organized group of assassins behind this, that among other things are related to the Democrats and the deep state, must be annihilated, without any mercy or restraint.
