Keeping the status quo on immigration will make the GOP the permanent minority party if it isn't already. A "wholesale amnesty" will destroy more than just the GOP.
The Heritage Foundation concluded that the cost of amnesty would be $2.6 trillion just for increased entitlement program costs. And the number of additional LEGAL immigrants who would join those who were the recipients of amnesty through chain migration, i.e., family reunification, would approach 70 million over a 20-year period, assuming there are only 12 million illegal aliens. We cannot assimilate such numbers. An amnesty would destroy the United States of America with the stroke of a pen.
It's what they have been striving for. Let welfare overwhelm the financial system of the country and bankrupt the nation. Its always been the endgame.
