I also would argue against the idea that Democrats WANT a more hispanic America.
Thats like saying ONLY Democrats decided a long long time ago to put the USA on top of South America in the hopes that all of those indigenous people south of the USA would want to come up here to live the fat life with the rest of us anglos.
What a stupid idea. The Democrats don't need NOR want a more hispanic America...I wouldn't mind some more of those peaceful middle easterns though.

I'm kidding!
As a human person (Democrat/Republican/Whatever) I recognize that the USA will always be a destination for people from all over the world..because they see greater opportunity here as opposed to whatever country they live in. Period.
If I was an alien from outer space dropped into the middle of a South America (PICK ANY) COUNTRY I would make my way to the US...more often than not. Why you ask?
because the USA is a BETTER COUNTRY.
It doesn't have to do with politics...it has to do with everything BUT politics.
If I'm a Democrat, I'm looking for the best possible way to manage those immigrants...those that want to be here, and those that aren't causing any trouble. I'm also looking for a way to use my limited resources to move out those that cause trouble. Key term, limited resources.
If I'm republican, I don't know what I want to do with people coming to the country. All I hear is "Secure the borders" whatever the F that means.
There is waaaay too much thought here being filtered through stupid political lenses, take off those glasses and look at this from a resource perspective. The US has only so much $, people, and materials to handle an overburdened immigration system...what do you do? And why hasn't our Government done anything?
