Politicians used to get into brawls. The last “real” fight in the federal legislature was in 1902, when a couple of senators got into a fistfight. Nothing of note happened since then until 1985, and that “assault” was one representative grabbing another by the tie briefly after a heated discussion. A couple of years ago, Representative Mike Rogers lunged at Matt Gaetz but was restrained, and nothing physical occurred (note that was from Republican inter-party bickering over the Speaker election). That’s all we have for the past 125 years. (There have been fights in state legislatures, but nothing federal.)
Going back to the beginning of our federal government, in 1798 you had one representative attack another with a walking stick, who then went and grabbed iron fireplace tongs, and they got into armed conflict. Nobody was seriously injured (which was lucky), but it was a real fight, and they were smacking each other in the head with them.
In 1856 you had another armed fight, this time a representative beat a senator with a cane in the US Senate chambers until the guy fell unconscious, and then kept beating him until the cane broke. The crazy thing is, some other senators went to intervene, but one senator pulled out a pistol and threatened to shoot someone if they interrupted it. Talk about brutal shit.
A couple of years after that, there was a huge brawl on the House floor involving around 50 representatives during a heated late-night debate. The only reason the brawl was stopped was because a guy’s hairpiece got knocked off from a punch, and when he put it on he accidentally put it on backwards, and it looked so ridiculous it made everyone stop and laugh.
Then a couple of years after that, a fight almost broke out between Democrats and Republicans over an argument over slavery, with folks brandishing pistols and canes and threatening to kill each other, but it didn’t get physical. Almost exactly one year after that incident (one year and a week later, actually) the US Civil War broke out.
And lastly, the primary reason why the government switched to a direct vote for US Senators rather than having state legislators elect them is because of a fight in 1887 in Indiana, where senators and representatives for the state brawled for 4 hours over a dispute regarding whether or not to send their state governor to the US Senate. The fight only ended when guns came out and they threatened to kill each other, and the Indianapolis Police Department had to get involved to prevent anyone from dying. Democrats and Republicans refused to even talk to each other in the state for a while after that, and as I said, that led to the adoption of a vote by the people rather than counting on state legislatures to sort it out themselves.
Compared to all that, things aren’t nearly as divided or violent these days. Even if we are starting to approach how things were prior to the 20th century, we certainly aren’t there yet.
