No they don't. At least where the majority in the local culture talks Spanish, and where the immigrant is Mexican.
There are plenty of such places in the United States. For example, 37% of the population in the Greater Los Angeles area use Spanish as a home language. This figure climbs to 40% in Miami, 72% in El Paso, and 43% in San Antonio.
This is actually true.
One of my friend who doesn't know Spanish stayed in El Paso for a week and he was like hunting for English stores. Learnt lots of Spanish words, we were wondering whether he went to Paso or Spain.. Again, not arguing there is a significant Spanish speaking population in places in the US. If there wasnt, we wouldn't be having this conversation. I'm simply saying that the illegal.immigrants aren't walking up to the voting boths, because of the risk of detection and subsequent expulsion. I'm here hiding, and I'm trying to sneak into a government office to falsely ID myself, to vote? That seems very unlikely to me. The article was stating that; Spend was saying that this isn't true in majority Spanish communities. I then asked for a community to be identified that would have a majority Spanish population, with the law enforcement being Spanish as well, as per BADs addition to the argument. Because I'm saying it's interaction with the government that gets you sent home; people trying to avoid going home have probably learned to largely avoid the government.
But yes, to concede your point, it is thick with Mexican immigrants in some places, just Latin Americans in general. Parts of Florida are like that too, and even when I was a kid, when I went to Texas to go to AstroWorld (6 Flags? It's been so long) I saw a bunch of really pretty Latin girls; it was my first time seeing so many Latin people in one place. I'm from Louisiana, was used to the local phenotypes

if diversity means pretty ladies, then dammit, put this fucker in a blender, my man.
Two words...
"Sanctuary Cities."
Side note - Realistically, El Paso and Juarez form one large interconnected community, the existence of a national border down the middle is largely irrelevant. The people are the same.
That's just one town, one example.
Alright, I will concede that point. I did some research on the actual policies of said sanctuary cities. I can concur that the diminished level of cooperation with federal authorities would technically constitute police assistance. But, take this with the grain of salt that this is law enforcement officers disagreeing with other, different law enforcement officers. The sanctuary policies aren't intended to harbor violent criminals, but I can see that the refusal to cooperate fully does cause 'gaps' so to speak, that allow violent immigrants to persist for longer than they should. However, I don't think the police allow crime to proliferate; I think they just aren't cooperative with federal law enforcement. Those monolithic Spanish communities you were talking about earlier? Cops rely on them to self report. The sanctuary city idea incentivized reporting of the actual bad hombres by the populace, to fill the gap in policing that I was trying to point out earlier. If they don't feel the need to cooperate with authorities, policing gets so much harder.
And none of that has to do with the fact that non citizen voting is really, really hard. Sanctuary city concept encompasses criminal deportation rather than voting issues, it seems. The protections that prevent double voting, prevent illegal voting. Otherwise, fuck illegals, people would just do this domestically if it were so easy a non citizen could do it. People would pay people to double vote, to hell with lobbying. You could literally buy the vote per citizen, or make the people up/steal identities yourself to influence the vote.
The reason you can't vote twice easily, is even more reason why an illegal can't. Do you see what I am trying to say?
If you can do this so easily in sanctuary cities, why havent underground conservative forces used this apparently very replicable technique to remove illegal influence, and restore balance?
