Correct. Trump has proposed no such touchback scheme. Cruz is desperate. And Cruz supported legalization, which is amnesty.
What Trump has proposed is sending illegals home, then letting “the good ones” back in. His son Eric Trump wants to make sure you understand that second part.
Now, touchback was a scheme whereby illegals had to go to their home countries, then they’d be eligible to return to the USA. Not all would hve gotten back in.
IOW, they’re the same thing. The Trumpsters are in denial about that, but it’s a fact.
