You are right. Its not going to happen and it won’t be millions of people.
To be precise Newt said that the american public (not him) could not stomach watching people pulled out of their homes. Can you just imagine a couple of days of the MSM televising the hysterical people being put on buses and sent to detention camps on their way to being deported. Those CNN cameras would be everywhere. Listening to Christianne Amanpour harp away about the evil right wing govt would be enough to make you sob.
What Newt did not say and he should have is that studies show that only about 20% of the illegals would come out of the shadows if offered amnesty/citizenship. Most illegal aliens have no desire to speak english or become US citizens. They are parasites, just here for the freebies and to make enough money to send home and then hopefully save up enough to go back and buy a house in Mexico.
So if we have 12 million illegals 20% is 2.4 million. Out of that group probably only about 70% or less would meet the tight criteria of speaking english, wanting to apply for citizenship, length of time in the US, paying taxes, ensconced in the community etc. So 1.68 million get to stay and then we enforce the laws so the rest will self deport or get deported if they get caught. Once you secure the border properly and take away the magnets like jobs, education, and healthcare they won’t want to come anyway.
I would rather do it that way than someday having the Democrats get a majority back and just pass blanket amnesty and no border security.
There is apparently no really good solution to this dilemma, but I like your analysis. Might work.
