You can convince yourself of anything to support Trump.
The 20 million illegals that are here now is bad but having them leave and come back with their families legally, which would be roughly 60 million, would be good.
Contrary to what you want to believe, increasing the number of 3rd worlders in this country for the American taxpayer to take care of will not solve a problem only increase it.
If they come back in, it won’t be Trump’s fault.
