800k is only the people who signed up for DACA. There are about 3.5 million people who were brougt here as children that they want to make citizens of.
Recent study on chain migration said the average new citizen brings in 25 relatives.
for ease of math lets just say 20 times 3.5 million. 70 million new immigrants who will vote for handouts over hard work and assimilation.
That's the goal.
