To the Democrats the cartel control in places like Mexico is likely something they laugh at and think "a bunch of amateurs".
Why wouldn't they?
They can violate the Constitution without consequence for them.
They can have evidence against them and make sure the media never talks about it while saying it is "debunked".
They can be caught and sent to prison and often walk right out of prison the same day.
If you can commit crimes and reap all of the rewards without any punishment why would you even consider stopping the crime spree?
As one person in a comment section put it...
"It is like they caught a jewel thief and let them keep the jewels."
