Illegals voting has nothing to do with the demographic switch although they are the cause of it. Unchecked illegal immigration has beget a nation of American born children from the illegals that are now coming into voter age. And it will only get worse.
Illegal immigration is a problem, but legal immigration is a much bigger one.
That's part and parcel of what I am talking about. There is no birthright citizenship for the children of illegals, and that is a problem that needs to be addressed as well. The 14th Amendment applies to people who are "subject to the jurisdiction of" the US. People don't generally understand what that means.
That said, we who want to enforce immigration laws, deny birthright citizenship to the children of illegals, jail employers and those with fraudulent SSN's, and all the things we need to do to regain our country, are probably such a small percentage that we can be counted on the fingers of one hand. Can we get it? No. But we can take baby steps to regaining control of our own demographic. First is illegal alien voting and gaining control various states so that a protected base remains intact.
