One metric that you might use is the percentage of Hispanic population. Taking four year old data from the census, and you get:
The logic of your post astounds me, if you're actually serious.
First off, 'Hispanic' doesn't begin to just mean "Mexican" let alone 'illegal alien" or any of the other narrow criteria you're seeking to use it as. Look the term up. It's quite broad actually. I know a number of Hispanics from the Philippines. And yes, here legally.
Tallying up whatever "percentage of Hispanic population" nonsense is painting with a ridiculously large brush that has little to do with this entire subject other than the most base-level stereotyping.
Consider that this map is based on four year old census data and that the southern border is relatively porous then the question becomes if the majority of the people in a geographical area are from Mexico, what rights do the minority (US citizens) have to take action against the majority from Mexico?
Again, astonishingly terrible "logic". Are you actually serious? Once more, Hispanics are not just Mexicans, and not synonymous with 'illegal aliens' and so don't all belong to some make-believe non-citizen majority against the citizen 'minority' that you're imagining from grossly misinterpreting a census map.
Even if one were to accept your premise that all of these people were in lock step as some majority of non-citzen "Mexicans" who've crossed the border to outnumber 300,000,000 Americans- that situation STILL wouldn't trump actual rule of law. We also don't just have 'majority rules' and toss everything else out either. (All of this is of course accepting your silly premise, which is so over-simplified it's a joke.)
I question what's wrong with people that they believe "Hispanics" are incapable of co-existing in a society with laws? It's just more of that "they're inferior!" attitude that people have that don't even realize that's what they're expressing. You HAVE to believe in the inherent inferiority of people if you think that they're incapable co-existing with rule of law. It's just that simple.
This as no different than me going to France and claiming I'm French, so give me everything I want. The French have every expectation of me to be able to understand that they have existing laws, and that I must obey them. I'm capable of it, and everyone knows it, so there's no excuse that I don't know any better, therefore their actual laws trump whatever I wish to be just because I show up and demand it. Therefore: I'd get told to take a hike out of THEIR country.
Likewise, an illegal from Mexico is no different: a human being fully capable of responsibility, and of understanding the legal structure of the US or any other country. There is no excuse that flies (the belief held by leftists of their inherent inferiority notwithstanding) and so they too get told: take a hike, we have laws, you're fully capable of understanding and obeying them.
