Pat has been warning us of the consequences of mass immigration since the early 1990s. If the status quo remains on legal immigration, the Dems will become the permanent majority party within a decade. There is a reason why the Dems have won the popular vote in six out of the last seven Presidential elections.
I don’t disagree with you, but I believe URBANIZATION plays a much bigger role than immigration in national political changes over a long period of time in this country.
