We are a minority - probably a permanent minority - since so many Conservatives support massive legal immigration, or are indifferent to massive legal immigration.
Immigrants vote 70%-75% Democrat, and their American born children vote 65%-70% Democrat.
The most successful immigrant group in the USA - Asian Indian Americans - votes 75%-80% Democrat!
Immigrant voter patterns have NOT changed in the last 40 years.
Politically, USA Conservatives have two options...
"Soft" Secession, which no one really knows how to do.
Or, make peace with the Republican Party, which is the only way to gain political majorities that can create limited real world change.
DJT will put Op Wetback to shame.
