Your argument has the presupposition that the political system is a working democracy. Stability, and security are not a given for all.
The only reason that this doesn't happen more often is the electorate is mostly disengaged from the races that do matter, and tied down by partisanship.
What are we supposed to do, switch from democracy to vigilante murder as a system of government?
Plenty of sensible policies have popular support in America and have done for a while. Americans are not as dumb as their politics would suggest.
The path to improving it does not go via vigilante murder.
Some form of immigration control now has majority support. Should people go round executing immigrants because that would be more directly democratic?
Democracy generally works well, and America becoming a poster child for "Why Democracy is bad" is a development that could lead to real horrors, at home and across the globe.
You don't have to condone political violence to support more democracy to avoid it. Even in nations, like the US, where political violence is celebrated every single day.
Perhaps the problem is that democracy isn't really any different than any other form of country-level government. Perhaps we lost for ever when our ancestors started founding cities a few thousand years ago.
Could it be that you're part of the privileged and hence why you prefer the statu quo not to change?
I don't mean this sensationally, but I do have to say it: you're promoting violence by saying this. Maybe indirectly, but it still leads to violence.
Money, in the US, is speech. That means that the richest people in the country have the most speech. They are heard the most by politicians because they put those politicians into power through their speech. This is done through mass communication in the media among other things. But it also happens through campaign donations, PACs, and whatever other interest groups.
When a group of people tries to "vote them out and pick people who will", inevitably a person with more speech than them uses it to override the will of that group. There is a massive asymmetry of power, one that is near impossible to overcome:

As people continue to see their material conditions decline despite voting, they begin to see violence as the only solution. So when you say "just vote away the problem", you are promoting violence, because voting continues to prove ineffective.
Oh, and just to pre-empt derailing: I vote. In every primary. In every election. Local, state, and national. In every run-off election.
This only works in a proper democracy. The US is currently an oligarchy.
Im the US you see an inverse correlation.
Yuval Noahs nexus does a good job of nuancing what a democracy is. I can recommend reading that book.
Next time, in order to not repeat the same mistake, they shall have _expected_ candidates. That's what democracy is all about. /s
