Byron York has an article saying something we at VDARE.com have been saying for a long time:

Republicans are famously divided on immigration reform, but Democrats pretty much unanimously support it. There's a reason for that.
In stark, partisan political terms, continuing the high level of immigration of recent decades, and certainly increasing immigration as envisioned by many reformers, will result in more Democrats winning more elections in coming years.
"The enormous flow of legal immigrants into the country — 29.5 million from 1980 to 2012 — has remade and continues to remake the nation's electorate in favor of the Democratic Party," concludes a new report from the Center for Immigration Studies, which opposes comprehensive reform proposals like the Senate "Gang of Eight" bill. "As the immigrant population has grown, Republican electoral prospects have dimmed, even after controlling for alternative explanations of GOP performance."[More]
The study he's talking about is Immigration's Impact on Republican Political Prospects, 1980 to 2012,By James G. Gimpel April 2014 (PDF ). Neither York nor CIS manages to credit Peter Brimelow or VDARE.com for saying all this early and often, possibly because it they're scared of Media Matters and the SPLC.
One important point about the Democratic voting—almost all foreign countries are more left-wing on issues of like free speech, gun control, and socialized medicine than Americans are.
Few of them came to America because they preferred the "American way of life" as expressed in America's political institutions. They came because they preferred American dollars. But they're likely to vote to make things the way they are at home.
