My personal experience with even the most apolitical people tells me they are aware
As more and more Americans become aware, the Democratic Party is going to have lots of problems going forward
There's a reason the Americans have been fleeing the larger urban centers, and taxation and regulation are only parts of it. Large parts, but there's more. The schools have been indoctrination centers of focused anti-white racism. The neighborhoods are more and more resembling shooting galleries, and the white victims don't get coverage (the reality of Polar Bear Hunting was down-played as white racism, you recall?)
So Americans are encouraging their children to find jobs elsewhere, and planning on retiring someplace white. Because they're either racist or realists. Or may only racists are the realists, these days. The Rodents are certainly racists, just ask Nancy Pelosi and Mad Maxine.
