How many H1B visa holders become citizens eligible to vote for those "left leaning politicians?"
I don't think having an H1B helps you accelerate your citizenship application in anyway, and for many countries the wait for legal citizenship is decades long.
You didn't answer the question at all. Getting an H1B visa is merely the first step in a very long process towards citizenship. Decades long. For example, if you're from India and you get an H1B, it'll be roughly a decade before you can get a green card. From then you have a mandatory 5 year waiting period before naturalization. And this assumes a normal, functioning immigration process; something we definitely don't have in the US.
This can be sped up if they marry a US citizen, speeding up the process quite a bit, but it will still be several years. Now their children would be citizens, but that's another 18 years before they can vote. Politicians aren't known for playing the long game...
>Politicians aren't known for playing the long game
There are plenty of politicians who have played the long game, also political parties take actions on longer time scales than individual politicians. Stances that politicians take on issues often come down from the party anyway. Many politicians don't care about many issues, but they vote based on their party's stance. The blue party is staffed with all types of people, many of whom will live to reap the benefits of changed demographics.
Heck many politicians are still in office 18 years later! Look at Nancy Pelosi, she was in office for 38 years. That's multiple batches of anchor babies.
It's not that long of an investment. We have seen this entire country go from 99% white in most places to below 50% in most places, in ONE generation and that change is clearly visible in national elections.
I mean just look at the data, it's a story that tells itself. One party does indeed benefit from increasing diversity and they are also the party that coincidentally spends a lot of time working on initiatives to increase diversity.
It seems that you are using the term "Great Replacement" as a tactic to dismiss the argument and all the data by which it is supported because you have no real counter argument.
I also did say that the other side benefits from importing cheap labor. Which is why both parties seem to do very little to slow immigration no matter which is in power, despite overwhelming demand from their constituents to slow immigration.
