As big as the political problems the US has been having in recent years are, I don't think that's likely to happen in the short-to-medium term. But, if these problems just keep on getting worse, then eventually it may become a very real possibility.
Peter Zeihan makes the case in one of his books for why Alberta should leave Canada and join the US. I’m not Canadian or American and have no dog in the fight, but it’s interesting reading.
While Alberta is often called “the Texas of Canada” there is not a single Albert a that would give up their healthcare to join the US. In many meaningful ways their standard of living would plummet overnight - healthcare, education, safety, violent crime, life expectancy, etc.
Rape: 16x higher
Total Crime: 5x higher
Murder rate: 3x higher
Prisoners per capita: 6x more
.. and it goes on
... would you want your community to change like that ?

And why would the US's existing violent criminals move to Alberta?
Violent crime in the US is not evenly distributed.
So the better question is actually why is the average American such a violent criminal compared to the average Canadian? Answer that and you will have answered your question.
Likely lack of healthcare (desperation), lack of affordable education, debt, need to fill for-profit prisons, corporate lobbying to make regular people's lives worse, etc. etc.
> Violent crime in the US is not evenly distributed.
Neither is it in Canada.
If you want to cherry pick the "best" of the US and leave out the worst from any comparisons, you'd have to do that for whatever country you're comparing it to.
Nothing would "send" criminality there, over time any place joining the USA would become the USA, and by definition it would become the average of the USA (because it will be a part of the USA)
A lot of people like to think a place will become the USA in all the perceived "good" ways like higher potential salaries, lower income taxes, more freedom, etc., but they fail to realize a place will also become the USA in all the ways that make the USA so vastly different from every other developed nation (healthcare, education, violence, crime, etc.)
Your live is measurably worse because of it.
