OK, Marco... we get it. You don’t want to be Mitt’s VP. Loud and clear!
The question isn’t whether Rubio would have tried to get out of a hell-hole to better himself, it is whether the US had any legal or moral right to let him stay and grant him citizenship. Cuba is distinctly different than Mexico or any other country. US policy has isolated Cuba, for legitimate political reasons, but that isolation has increased the economic poverty and political persecution of those who dare to speak against the government. I view Cuban-Americans as primarily political refugees, not economic refugees. The minute the Castro’s are gone and Cuba becomes a democratic country, is the day that Cuban’s should cease getting a free pass. If the US took the open borders approach, you would get 40 million people flooding into your country from Mexico (including central and south americans) and Canada (we have lots of immigrants who would prefer to live in the US). The result would be economic disaster for America. If you cannot let everyone in, then you have to have laws to restrict access. And those laws need to applied evenly, regardless of whether the intended immigrant is halfway around the world or on your border. To do otherwise is to invite chaos.
