We’ve been doing it since the early 70’s, that’s at least two generations.
We did not talk about the "hispanic" vote then. It was a tiny minority, not considered American.
We did not talk about the Asian vote then, because hardly anybody had met one, outside of San Francisco or downtown LA.
We did not talk about "Indian Americans", unless you meant Navajos and Apaches. No one - and I mean no one - knew anyone from Bombay, as it was known to us then.
Cuba was a place that was thought to be temporarily run by a thug, and the 200,000 or so Cubans who were temporary Refugees in South Florida were supposed to be getting ready to go back and use force to take their home back.
California was 20 million people, about 4% of whom termed themselves "Spanish". The term "hispanic" was not used. "Chicano" was a radical epithet that Mexican Separatists (i.e., terrorists) used to describe themselves.
All the "minorities" we talk of now except the Africans were not here in any significant number in 1965. They flooded in only in the last 4 decades because of the vacuum created by the lack of American children, both black and white.
The people who aborted their children, stopped having more then 1 or 2 (called "Replacement children" by Ehrlich and others), are now in their late 60's and 70's. Like their standard bearer - the hacking, coughing, dying Hillary Rodham Clinton - they are fading into the past, as any suicidal race will. It only took a generation, as I said.
What you are seeing now is the death of the modern Marxist "Democrat" party: if it weren't for their alien replacements, they would not exist as a political force anymore.
So I stand by my statement. The America I live in now looks NOTHING like the America I grew up in. Had my generation actually reproduced itself and increased itself as all prior generations had - the Americans who had 10 and 15 children per family (my GG Grandfather had 15, all lived) - we would not be having this discussion now.
The Rat party would not exist as it does now. Abortion and Euthanasia would still elicit the horror that we felt when we spoke of it then. And the Clintons would be in jail cells, probably for embezzling from their menial county government jobs that they are only qualified to do.
