I posted this very thing yesterday. The Democrats think that they can replace American voters with foreigners. Because Dems think that foreigners will always vote Democrat no matter what. No. This is not correct. This is a false and condescending attitude.
Foreigners, illegals, etc. are not going to tolerate old washed up snow White hippies from the sixties being their representatives like the American Blacks have done for the last 50 years. It is clear that immigrants don't want the White Oligarchy, which is the Democrat Party, representing them. And, they don't want some latte sucking snow White Harvard pretty boy either.
Sooner rather than later, they will form their own Party to challenge the Democrats for power. And I think eventually they will win.
