They are not illegal aliens until they illegally enter the United States illegally.
That’s why I think the conclusion of the commercial will not be as expected.
And? Rent a clue, friend.
The commercial shows a woman traveling with a small child through desert and wilderness. Just where do you think they're going? Why would they be shown making such a trek, if the producers want us to assume they're legal immigrants?
Answer: They're illegals trying to break into the United States. In the original version (according to some on the thread), the end of the commercial shows them arriving at Trump's Wall.
Now quit advocating for these people, would you?
