I really think a wall would be extremely helpful- but at this late stage, it's only a part of what we need. We must have a reduction of legal immigration, end to chain migration, end of birthright citizenship for illegals/visitors/tourists, counterproof social security cards sent to all Americans, e-verify, increased penalties for employers of illegals, no social services for illegals, mass deportations, freezing of asylum applications at border, catch and return immediately for illegals getting across border. Even more to add to these things- but it would be an excellent start. But, so far, nothing.
