It's been going on for a while. Congressmen and senators have allowed threats of violence to control how they vote:

To quote the article, "Some of the reluctance to hold Trump accountable was a function of the same old perverse political incentives—elected Republicans feared a political backlash from their base. But after January 6, a new, more existential brand of cowardice had emerged. One Republican congressman confided to Romney that he wanted to vote for Trump’s second impeachment, but chose not to out of fear for his family’s safety. The congressman reasoned that Trump would be impeached by House Democrats with or without him—why put his wife and children at risk if it wouldn’t change the outcome? Later, during the Senate trial, Romney heard the same calculation while talking with a small group of Republican colleagues. When one senator, a member of leadership, said he was leaning toward voting to convict, the others urged him to reconsider. You can’t do that, Romney recalled someone saying. Think of your personal safety, said another. Think of your children. The senator eventually decided they were right."

That is not a well functioning democracy.
