Do you think they all should be deported?
There is no way that in the US we would roundup every illegal immigrant there are about 12 million of the illegal immigrants not only economically is that just an impossibility but that's not a humane way anyway to deal with the issue that we face with illegal immigration.
....To clarify, so you support a path to citizenship for undocumented immigrants?
I do because I understand why people would want to be in America. To seek the safety and prosperity, the opportunities, the health that is here. It is so important that yes, people follow the rules so that people can be treated equally and fairly in this country.
Eisenhower did it. He had millions deported.
